Charlie Thorn is such a good book! I say that about most books I read, but this one especially sticks out to me. I LOVE learning about history and Einstein, and some suspense just makes it better! This book lead me to lots of discussions with my dad, and I have to admit that I do love math! This is a really suspenseful, fun, exciting, and interesting book! Make sure to read the prologue, because it gives background knowledge that you need to understand the book. The best part is, if you read this book and love it, you can read more of the books in the series. Stuart Gibbs wrote more series’ that you can read! If you’re still intrigued, (which I certainly was) read this book!

This book is for any kid who loves fiction and action. What I liked the most about the book, is that two main characters (I'm not telling who!) form a special bond that shows throughout the book. If I were you, I would chose this book!!!!!
