        This book is a must read, and I for one LOVED it! When Cruz Coronado gets accepted into Explorer's Academy along with 23 other students, he's never been happier. He makes friends, like Emmett and Sailor, and his aunt even works there! However, this is the school where his own mother was killed, and Cruz suspects it wasn't an accident. His mother was involved with something dangerous, and those same people who killed her are after Cruz too. Throughout his school missions that were assigned for him and his friends, he discovers that something always goes wrong. Someone is ought to get him, but why? And who is Nebula? With his friends help, can he find out the answer to his life and his mother's death, or will Cruz's nemesis get there first? I rate this book 5 stars for the action and adventure. This book taught me a lot of stuff, and I hope you guys love this book as much as I do!

                  I thought I wasn’t going to like this book! I LOVED it! Cruz Coronado was selected to be one of 24 students from across the globe to attend the famed Explorer Academy in Washington DC. When he was very little, his mother had been killed in a tragic accident in a lab there. Then Cruz finds out that maybe the accident wasn’t an accident. He discovers that the same people that killed his mother are after him too. It is a quick and easy read, but very enjoyable!
