This book isn't a Rebecca Caudill nominee, but a teacher recommended this book to me and I loved it! It is about a mysterious mission that four gifted students find themselves mixed up in. The reader gets to try and figure out the mysteries and clues with the characters and the book is full of plot twists and turns. If you like books like Harry Potter, you will love this book! This is probably one of the best books I've ever read. It is the first book of a series so I am excited to start reading other books in the series.
