I didn't expect to like this book so much.

I've never read anything else by Blake Crouch. I figured this would be a fun, light, thriller. At the end of the first chapter, I figured I knew where the story was going, and I was right. Along the way, though, the book also asks some questions about what defines our personality and what makes us unique in the world.

I usually give 3 stars for books that are good but not great, and four stars for books that I really want to recommend to people. I really almost gave this one four stars. I'm going with three because Crouch's writing style -- lots of short, choppy, sentences -- is annoying. I wish I could give three and a half.
