By Frederik Pohl
Barry di Hoa was doing pretty good, considering. Because he had been locked up when he was younger due to his mental illness. He describes it thus: "I had a 'psychosis' that closely resembled 'schizophrenia' of the type once called 'manic-depressive.'" He goes on to add that it, "came from my genetic heritage; my mother and my father just happened to carry some very rare recessive genes." Fortunately there was treatment that enabled Barry to live a normal life, with his symptoms under control. Unfortunately, it required injections several times a year, injections that he would have to have all his life.
Barry lived on the moon and worked with antimatter fuel pods. Antimatter is very dangerous stuff but Barry was good at his job. And it paid very well. He had a girl friend that he loved and who loved him. The girl friend, Alma, used to belong to a religious cult, the Penitential Church of the Millenium, aka Millenarists. Which was basically a death cult that believed merely being alive was a sin, as was having children. And the best thing to do was kill yourself. However, Alma tried hanging herself but only nearly died. That brush with death gave her a new outlook and she left the cult.
So what does this have to do with the story? Quite a lot. Because a ship from a colony plant, Pava, had arrived on the moon and Barry was in charge of loading their large order of antimatter fuel pods on their vessel, the Corsair. The captain of the vessel, Garold and his close friend, Reverend Tuckman, were both Millenarists. And many of the colonists back on Pava are also Millenarists. They had legitimate reasons for their large order of fuel pods, though, so Barry thought nothing more about it.
Back to Alma, who had an ex-boyfriend, Rannulf. Who no longer wanted to be her ex. Surprisingly, Rannulf declared that he would be joining Garold on board the Corsair, to become a colonist on Pava. Before he left, though, he wanted to talk to Barry privately. Barry agreed to meet with Rannulf and as a result he was drugged and stashed in one of the freezer capsules by Rannulf used for space travelers because of the immense amount of time required for long trips, in this case, twenty five years from the moon to Pava.
So Barry wakes up on Pava, and even if he did travel back to the moon, it would be fifty years since he was kidnapped. Alma would be fifty years older and Barry would still be a young man, thanks to the freezer capsules.
Life on Pava is harsh and the colony is struggling. Mostly because the planet is tectonically very active. They had recently experienced a serious earthquake that had destroyed a dam they were using for hydroelectric power. Although Barry is regretting his lost life on the moon with Alma, he gets to work, doing his part to help the colony survive. But he knows his medical issue will soon become a problem and that the colony doesn't have the medical experts or equipment to make the medications he needs in order to stay sane. The best the local doctor (who is actually a dentist) can do is give him medicines to combat depression and to calm him down when he is manic. Which sort of works, until Barry starts abusing the anti-depression medication to boost his spirits. And then the colony experiences another major earthquake and everybody is miserable. Except the native peoples, large caterpillar-like creatures, who had been quite helpful to the colony people, providing much needed labor. But they have all disappeared, for reasons unknown, and their contributions to the humans' survival is sorely missed.
Finally Barry figures out something that was quite obvious from the beginning of the story, namely, Garold's real intentions with all those fuel pods of antimatter. Garold is going to do what so many religious fanatics love to do: kill nonbelievers.
My main problem with this book was the interrogation technique of telling the story. Person or persons unknown are questioning Barry and he is trying to explain his actions. I found that style of telling the story boring. So boring. The reader doesn't find out until quite far in the story who is doing the questioning. We also don't find out why until near the end.
Like so many novels these days, the book was too long. Editors don't like edit any more, I guess. I don't think this story needed over 300 pages in order to be told.
Another thing I didn't care for was the characters. Most of the characters are annoying at best, even Barry with his pathetic obtuseness. The most interesting characters were the natives but they don't get a lot of attention from the author. I guess they are only there to draw a contrast between the shitty humans and the virtuous caterpillar people.
Finally, the title, Voices of Heaven. I never figured out if that referred to the caterpillar people or the religious fanaticism that seems to have overtaken the humans of this imaginary future.
