Reading this book felt like reading pretty good fanfiction. The writing wasn't awful, but it wasn't great either. I didn't feel emotionally connected to Felix or very interested in his personal thoughts or the ridiculous "Engine", but I did enjoy reading about his battles, and I enjoyed the ants. That can't be said at all for Jack Crow, who I read about 15 pages of and quickly skimmed the rest. This book could have been much improved by cutting out all 200 pages of Jack Crow and focusing on Felix.
