Seminal SF classic.
The White Tiger, by Aravind Adiga
The Gargoyle, by Andrew Davidson
World War Z, by Max Brooks
I'm usually the last person to go in for zombie entertainment of any kind, which is why I was surprised by how much I enjoyed this book. I could not put it down.
The Android's Dream, by John Scalzi
It's hard not to like any book that dares to start with a fart. Although my Canadian paperback edition suffered from an overabundance of typos, for some reason. A great read regardless.
