I've become quite a Greg Bear fan lately--for Christmas I got both The Forge Of God and Anvil of Stars, and I'd finished both of them by Jan. 5. Delighted with them, I picked up Heads at a local bookstore, although I admit having some doubts about the book after looking at the blurb. It seemed an awful lot to juggle in such a small space--410 cryogenically stored disembodied heads, along with Moon colony politics and an attempt to reach absolute zero which might change the nature of matter and of time itself, all within about 150 pages. At the same time, I've ocasionally thought Bear was a bit too drawn-out, so I decided I'd give it a try.
Curiously enough, spacetime was indeed apparently affected by Heads, because I must have seen the future--I was right, and it was all a bit much to handle in such a short book. By necessity, Bear's writing was much more expository than usual, and I didn't find that very satisfying. The story was promisingly offbeat, but behind the story was a blatant parody of Scientology--now, I'm not a Scientologist, nor do I know any Scientologists and I have a healthy skepticism of any religion founded by a science fiction writer, especially one that espouses Body Thetans--ghosts of an alien civilization--as the source of physical illness. It's a valid target, but somehow I'd like a touch more subtlety, a soupcon of sophistication about it...perhaps that's a bit much to ask of a book titled after decapitated noggins...
At any rate, it's a good story, with an effective and creepy climax...it's merely the baldness of Heads that detracts.
