I loved this book it was so exiting and fun and mysterious. it was a fun book with plot twists and many other exiting things.

I read this all in one day! It was a page turner and I literally couldn’t put it down. I read the sequel what was really good as well.

Another awesome book by Stuart Gibbs It has an interesting plot, and really hooks you in too the story. A good read.

I loved this post I thought I ought to post it again: An awesome book that has mistery, action, adventure and science. Great plot, involving Einstein, family problems and a lot of great characters (the main character is a girl, which for me is so cool because most books the main character is a boy), but it doesn't involve anything that has to do with Judaism, sou if your looking for a book with Judaism contents this is not the book for you. If you're looking for a book with the characteristics I described or you liked the plot IT'S A DEFINETILY READ.

This book was so good. It showcased a girl that is very talented but ends up uses her strengths to good use. This is my all time favorite book and it is a must read.
