Android Dreams
I recently finished John Scalzi's Andoid's Dream. I've said it before, but I've always been a huge fan of Robert Heinlein and John's writing reminds me of his. This book is John's 3rd sci-fi novel and his maturity over time as a writer is obvious. I think Old Man's War is my favorite Scalzi book so far (although Ghost Brigades rocked too), but this is a fun, interesting book. It has great childish humor (passing gas is a common Scalzi theme) like Agent To the Stars, but is more traditional (but still very creative) in topic and plot.
Now on to River of Gods by Ian McDonald. Never read any of his stuff before...
