*Actually 4.5 stars.This book was so much fun to read! The pace is probably the best feature about this book, never letting the reader get bored or disinterested. I loved the nerdy pop culture references, and they surely aren't for the non-nerdy types. If you're not into that kind of thing then I'm willing to bet you ten bucks that you'll just get annoyed and hate the book. I also really enjoyed the exposition in this book, a literary device that can really make or break a story. If you overdo it, it ends up heavy and boring. Cline executes it perfectly though, setting up the backstory just enough to draw you in. The only reason I gave this book 4.5 instead of 5 is that I found the dialogue choppy at times.Overall, great! An engrossing, fact-paced, high energy geek book!
