Partials is one of the best books I have ever read. I loved the way the two different "species" were introduced. The ending completely surprised me. When Kira was betrayed by Samm (Yes, I spelled it right), I almost stopped reading. I really liked this book, but it was very bloody and long. It was over four hundred pages. I think that it is more for older kids though.
This book is amazing, it had a a plot that really could happen. Humans create a race of half-humans, half-machines. I really enjoyed this book, and I hope a lot of other people will too. I think that this book is the best sci-fi book I have read during this goal.
