The Colossus Rises

Jack McKinley is an ordinary kid with an extraordinary problem. In six months, Jack is going to die.

After Jack collapses in the middle of a busy street, he's whisked off to a strange hospital in a strange place. There are armed guards and weird kids and fantastic creatures, not to mention no parents, no phones, and no possibility of escape. The place is run by an odd professor named Bhegad, who tells Jack that what's killing him is a genetic trait inherited from the prince of a long-lost civilization. It's destroying Jack by making him too strong too fast. He'll need to stay strong, though--because it's up to him to save the world.
