This book was captivating and disturbing in equal measure. It was like watching a horrific train wreck unfold, I couldn't stop reading even though it was going downhill. The protagonist is in a wasteland of his former life - of the former planet! The book description depicts it as a twisted love story, but that was such a small part of the total it barely warrants a mention. Most of it tells the story of Snowman, his best "friend", Crake, and the object of both their desires, Oryx, and the "Crakers", and how they all got there. The first half goes forward and backward at once, as Snowman makes a journey for supplies and also recalls past events leading to the virulent apocalypse, then all is in the present as he reaches Crake's dome, and he tries to figure out what is next.
