The basic plot is that John Smith (main character) has just arrived in Paradise, Ohio. He is 15 and has been hiding out from the Mogadorians. Terrifying aliens that plan on killing him and the other nine Loric children who have sought refuge on Earth. Loric's people are much like people on earth and had a plant like earth then the Mogadorians destroyed there plant. The Mogadorians are picking off the surviving kids in numerical order. The first three are dead and John's number is up. Will his Legacies, his defining super powers, develop in time for him to fight against the enemy?
I loved the book. It has action and adventure. It also has a good plot to it. The book is for Si-fi fans and however likes action and adventure. The book isn't that long 448 pages and if you like it, it reads fast.
