Adventure, danger, and a thrilling global mission await 12-year-old Cruz Coronado as he joins an elite school for explorers.

Cruz leaves his tranquil home in Hawaii to join 23 talented kids from around the globe to train at the Explorer Academy with the world's leading scientists to become the next generation of great explorers. But for Cruz, there's more at stake. No sooner has he arrived at the Academy than he discovers that his family has a mysterious past with the organization that could jeopardize his future. In the midst of codebreaking and cool classes, new friends and augmented reality expeditions, Cruz must tackle the biggest question of all: Who is out to get him, and why?

Readers can get in on the excitement with puzzles and codes embedded throughout.

    This book is great! There was a picture of this chart that had symbols that means the alphabet.There were lots of codes in the book. It was fun to break the code and see the message. I can't wait to read the second book in the series, The Falcon's Feather!
