Skinned

Very good sci-fi book.  I liked Skinned by Robin Wasserman because it was a look at what the future could be, and it made me uncomfortable.  The premise is that you can get a new computerized body and download the contents of your brain.  Wasserman thought of a lot of details about the complexities of this existence that made it seem real (and unpleasant.)  This book takes place in the future, after nuclear devastation, disease, plagues, and floods.  You name it.  There is a strict cast system in place.  There are drugs to change your mood to whatever you want.  She describes a lot of futuristic technology (some maybe not so far in the future.)  I thought this book did a good job of setting the scene and provided a lot of food for thought about what is "life?" This is the first book in a trilogy, and the other two books are already out, I believe.  I think some good companion reads would be Uglies by Westerfeld or Unwind by Shusterman.
