The Code of Magic

There's a monster in Alex's backyard. He doesn't know how it got there, but with his parents refusing to help, Alex must capture it on his own. When he does, a monster hunting Keeper comes to claim it. Alex follows the Keeper to the world of Edin, a preserve for monsters run by magic-wielders. Aboard the Keeper's airship, and with his giant socket wrench-wielding monster companion, Alex must learn the art of magic if he hopes to stay in this wondrous world. But as he trains with the other children in the fortress of Babili, rumors begin that the Heretic Pharaoh has returned, and Alex's new home is in danger.
