[b:Oryx and Crake|46756|Oryx and Crake|Margaret Atwood|http://d.gr-assets.com/books/1327896599s/46756.jpg|3143431] is quite good, but The Year of the Flood is better yet. I found myself identifying with both Ren and Toby, and I was really drawn to their stories.
After reading this book, I'm in mild danger of becoming a 'prepper'. I want to borrow a book about urban gardening, and dig up my entire yard. This book is 'realistically' scary, and yet very enjoyable.
One last thing- The Year of the Flood ends about an hour after Oryx and Crake- I got a kick out of that.
