The author seems to have had a lot of trouble deciding what type of book he wanted to write. Hot Sleep begins as a fairly typical future-urban coming-of-age tale of a telepath. It soon degenerates into a B-grade thriller, then jets off into space and ultimately becomes a future history. Despite this, it ultimately comes together to form a very impressive first novel, with the truly epic scope that only science fiction has ever been able to do well, and a beautifully haunting ending. While it's a pity about some of the early parts, the book has a wonderful unity of vision, and it reminded me, as so few books I have read recently, why I love reading sf.
