Ballroom of the  Skies was John D MacDonald's sixth published novel, coming right after  Wine of the Dreamers and before The Damned. Like  Dreamers (his other early science fiction novel), it originally  appeared in hardcover, published by Greenberg in what must have been a fairly  limited run. But instead of enjoying a subsequent paperback edition (like  Dreamers), it was reprinted in a magazine nearly two years  later, included as one of the two novels in the Winter 1953 issue of Two  Complete Science-Adventure Books. Then, like Dreamers, it went out  of print and remained largely forgotten until both novels were reissued in 1968.  As a result I think it's safe to say that, until 1968, Ballroom of the  Skies was MacDonald's most obscure novel ever.
The book is usually  referred to as a "companion piece" to Wine of the Dreamers, in that  both books are JDM's only novels of straight science fiction, they both appeared  at about the same time, and they both are built around a similar premise: that  mankind's ageless, unsolvable problems are the result of alien influence and  control. Hardly a new or unique idea, the "aliens are among us" idea goes back  at least as far as 1931's "The Earth-Owners" by Edmond Hamilton and has been  popularized most recently in the television series Battlestar  Galactica with their "skin jobs." The publication of MacDonald's novels  coincided with the cresting of a wave of anti-communism that occurred in the  United States in the early 1950's, along with the concurrent fear that our  enemies were secretly infiltrating our society, and they looked just like  us! This "Paranoid" school of science fiction enjoyed a huge surge of  popularity that decade, both in the printed word and in the movies, and it  continues today, only slightly abated, with television series such as The  Invaders and, more recently, The X-Files.
MacDonald's spin on the  idea was that the aliens aren't actually among us but they control us, or some  of us, from afar. In both of his novels this control is purely mental, where the  outsiders are capable of entering and taking over our minds, enabling them to  use our bodies for their nefarious purposes. It is those very purposes that  differentiate JDM's two works. In Wine of the Dreamers the controllers  are unaware of what they are doing, believing that the dreams they have where  they take over other life forms are just that: dreams. In Ballroom  there is both purpose and intent: the aliens know exactly what they are  doing.
The post-World War III  Earth of Ballroom is a different world from the one of 1952, but only  by degree. With Europe finally a wasteland, and the United States damaged and  out of natural resources, the new world is a reorganized group of aligned  nations, with reunited "Pak-India" the world's industrial leader. Coalition  nations have formed out of necessity, with the fascist South America (led by  Brazil), China and the Middle East (now called Irania) providing the new  friction that seems to be leading to a fourth world war. Dake Lorin is an  idealistic newspaper columnist who has taken a year off in order to work with  another idealist, Darwin Branson, a man who has been asked by the President of  the United States to work with the other powers of the world to hammer out some  sort of mutual assistance pact. It has taken a full year of "cautious dickering  [and] meetings in furtive places" in order to get to where he is at the  beginning of the book, nearly done, awaiting only a meeting with the  representative from Irania to obtain their final agreement.
As he waits for both Dake  and the representative, he is visited by a young couple. In the time it would  take to wash his hands they have killed and replaced him with a dronish  substitute. They disappear in a flash, "flickering like black flames" from the  roofs and ledges of the nearby buildings before vanishing altogether. Dake  arrives with the representative and is astounded when Branson basically scuttles  the agreement by offering a cynical deal with the Irania government. A disgusted  Dake quits and resolves to risk life and limb by publishing a column revealing  his work for the past year, showing readers just how close the world came to a  lasting peace.
The enervation of society  in the United States is wonderfully described by MacDonald early in the novel,  where he paints a post-apocalyptic world all too familiar to readers in  2009:
"The war of the seventies  had caused a further moral deterioration. Man sought escape in orgy, in  soul-deadening drugs, in curious sadisms. Along 165th Street the fleng joints  were in full cry. In the mouth of an alley three women, loaded to the gills with  prono, were mercilessly beating a Japanese sailor. Giggling couples pushed their  way into a dingy triditorium to rent the shoddy private rooms where the three  gleaming curved walls were three-dimensional scenes for a life-size,  third rate  showing of one of the obscene feature shows turned out in the listless Hollywood  mill. Censorship restricted such public showings to heterosexual motifs, but  further uptown, private triditoriums showed imported specialties that would gag  a gnu."
That was written in 1952,  and one wonders if his prescience was too kind.
Dake needs to find a  newspaper willing to publish his expose, and that won't be easy in this  restrictive and censorious new society. He finally finds a run-down rag who will  run it as a paid advertisement, but it will cost Dake far more money than he  has. He decides to ask his on-again-off-again girlfriend Patrice Togelson for  the money, and flies from New York to Philadelphia to meet with her. Patrice is  wealthy, a result of a family oil fortune and a hard-headed, pragmatic business  sense. Despite her misgivings, she gives Dake the money and he returns to New  York to begin typing out his story.
That's when the  really strange things begin to happen. He starts hallucinating,  imagining that he is suddenly in a cow pasture. Then back in the newspaper  office, he starts typing gibberish, later seeing a tiny reproduction of  Patrice's face on each key, faces that become smashed and bloodied and cry out  in pain as he strikes the keys. After hearing a report on the radio announcing  that Darwin Branson has died suddenly, he drives to the morgue to inspect the  body, finding strange anomalies. Convinced that the corpse is not Branson, Dake  begins questioning his own sanity. Then he meets Karen Voss.
Karen possesses strange,  extra-sensory powers that the reader is made aware of, but not Dake. She takes  him under her wing and introduces him to her friends. (She is described as  having "curiously pale gray eyes," so MacDonald fans know instantly that she's a  good guy.) After much more unexplained phenomena, including one that literally  drives Patrice to insanity, Dake learns who Karen really is and suddenly finds  himself on another world, in training to be able to do what Karen does and  ultimately return to Earth.
Brimming with ideas and  predictions of the future, Ballroom of the Skies almost chokes to death  on its own detail. MacDonald is obviously taken with his future society and  writes page after page on its politics and morality. It's tough going early on,  and the first half of the book has lost more than one reader I am aware of.  Thankfully the story begins humming along nicely once Dake is carted off to  God-knows-where (actually a planet called Manarr), and when he returns to Earth  MacDonald writes some of the best suspense of his early career. But getting  there can take a lot out of the reader.
 
Writing in the third person  allows the author to reveal things that Dake is unaware of, and it is this  device that ironically both helps and hinders the narrative. We see bits and  pieces of the alien insurgency, explaining the oddities that leave Dake  wondering about his own sanity. These scenes often become overly confusing and  slow the pace of the story considerably. At one point MacDonald completely  departs from both the plot and his own writing style when he offers a brief  description of Manarr. It's a wonderfully written paragraph that reads like he's  channeling Bradbury, but jarring nonetheless:
"It was a fine summer  morning on Manarr. The sun beamed hot on the shallow placid seas, on the green  rolling traces of the one-time mountains. The fi-birds dipped over the game  fields, teetering on membranous green wings, yelping like the excited children.  Picnic day. Picnic day. Everyone was coming, as everyone had always come.  Hurrying from the warm pastels of the small houses that dotted the wide plains,  hurrying by the food stations, the power boxes. Hooray for picnic day. The  smallest ones set their tiny jump-sticks at their widest settings and did crazy  clumsy leaps in the warm air, floating, sprawling, nickering. The maidens had  practiced the jump-stick formations and groups of them played towering, floating  games of leapfrog on the way to the game fields, spreading wide their skirts,  swimming through the perfect air of this day... Picnic day. Today there would be  water sculpture, and sky dancing, and clowns. Day of laughter, evening of the  long songs, night of mating. Time for work tomorrow..."
His depiction of some of  the social problems in this new order are insightful, none more so than the  plight of "the Negro":
"Though the war of the  seventies had done much to alleviate racial tensions in the United States, there  had still been small though influential Negro groups who had joyously welcomed  the dominance of a dark-skinned race in world affairs. They had soon found, to  their dismay, that the Pak-Indians were supremely conscious of being, in truth,  an Aryan race, and brought to any dealings with the Negro that vast legacy of  hatred from the years of tension in Fiji culminating in the interracial  wars."
His ruminations on a  has-been United States sounds like something out of today's global warming  controversies:
"We had it, he thought, and  we threw it away. We ripped our iron and coal and oil out of the warm earth,  used our copper and our forests and the rich topsoil, and hurled it all at our  enemies, and conquered them, and were left at last with the empty ravaged  land."
As he did in Wine of  the Dreamers, he presents a newscast depicting current affairs, both as a  means of exposition and a way to vent his predictions:
"Massacre in a religious  encampment in Iowa. Fire razes abandoned plant of Youngstown Sheet and Tube.  Gurkah Air Force takes long-term lease on Drew Field in Florida, in conjunction  with the missile launching stations at Cocoa. Maharani kidnap attempt foiled.  Skyrocketing murder statistics blamed on prono addiction, yet growers' lobby  thwarts legislative control. Bigamy legalized in California after Supreme Court  review. Tridi starlet found dead in bed. New North China conscription planned.  Brazil develops deadly new virus mutation. New soil deficiency isolated at  Kansas lab. Texas again threatens succession..."
MacDonald saves his most  savage predictions for his own country, as he envisions a tired, corrupt and  jaded former superpower, one where there is no hope for the next  generation:
"He felt uneasy riding  through the dark streets with money in his wallet. Philadelphia was infested  with child gangs. The dissolution and decay of the school system had put them on  the streets. They had the utter, unthinking ruthlessness of children in all  ages. The guerrilla days had filled the land with weapons. Put an antique  zip-gun in the hands of an eleven-year-old child from a prono-saturated home,  and you had an entity which thought only in terms of the pleasing clatter of the  gun itself, with imagination so undeveloped as yet that the adults who were  ripped by the slugs were not creatures capable of feeling pain, but merely  exciting symbols of an alien race..."
Sound  familiar?
Raymond Carney, an English  Professor at Middlebury College, wrote an essay on MacDonald's science fiction  novels back in 1980, titled "John MacDonald and the Technologies of Knowledge"  and published in the JDM Bibliophile (#26). He called the novels  "extraordinary science fiction" and concluded that:
"...MacDonald avoids being  trapped by any of the various plots he plots. The success of his writing depends  on his ability to deploy and negotiate the intersecting technologies of law,  bureaucracy, history, and memory more deftly and humanely than even the best of  his readers. The positive value that is affirmed by these novels is nothing very  complicated --  it is something very [much] like an almost childish tenderness  and affection for particular people and things. The value MacDonald appears to  cherish above all else is simply the thoroughly human capacity to love, to play,  to inquire, and to explore, in short man's ability by virtue of his mere  humanity to resist any inhumane system that would contain or control  him."
I think that sums up all of  MacDonald's writing, not just his science fiction, and it reached its apogee in  the Travis McGee novels.
As I mentioned in my  posting on Wine of the Dreamers a few weeks back, the fact that  Ballroom of the Skies originally appeared in hardcover allowed  MacDonald to enjoy some of the only contemporaneous book reviews he would  receive in his early career as a  novelist. The Shines report that the book  received notices in the New York Times, the New York Herald  Tribune, the San Francisco Chronicle, the St. Louis Post  Dispatch, Saturday Review, along with a smattering of science  fiction magazines. The reviews were generally favorable, although many of the  reviewers definitely understood the novel's shortcomings. Startling  Stories pointed out that "the story gallop[s] off in all directions," and  the Herald Tribune noted that the "novel is a little less successful  than its concept." The Saturday Review correctly said the "material  often escapes the author's control," while the St. Louis Dispatch  presciently opined "Mr. MacDonald should go back to writing detective  novels."
He did, returning only once  more to science fiction in 1962 with the breezy, comic novel The Girl, The  Gold Watch & Everything, a book the author rarely even considered  science fiction, but fantasy.
Update (1/19/2015): In March of 2010 I decided to write a piece on MacDonald's January 1951 science fiction novella, "Hand From the Void," a work I had not read before. I discovered that it was, in many respects, an early version of Ballroom of the Skies, a fact that I had never known or heard about. You can read the posting here.
