This came as a pleasant surprise after an abortive attempt at Oscar and Lucinda. I found his prose largely prosaic, but he does turn out a decent sentence every so often. The opening one:
Harry Joy was to die three times, but it was his first death which was to have the greatest effect on him, and it is this first death which we shall now witness.
seems to leave one unresolved by book's end.
This review makes the obvious connection to Vonnegut and I echo some of his qualms.
