Thirteen-year-old Jack McKinley has been cursed with a genetic abnormality that is giving him amazing superpowers--the catch is that his body cannot handle them as fast as they are developing, and they will eventually kill him. To preserve his life, and maybe the lives of all humanity, he will have to find the Loculi hidden in the Seven Wonders of the Ancient World. He has found the Loculus at the Colossus of Rhodes: now he is on to the Hanging Gardens of Babylon.
