These growing pains are...monstrous.

Thirteen-year-old Lucas Wright is hiding out for his life. The space research station he and his family live on has been invaded by a dangerous alien. One by one each member of the station team has disappeared. Captured. But why?

Part of the answer is revealed when Lucas stumbles upon a series of strange cocoons on board. Inside he finds the imprisoned crew members, including his family. Even more horrible, each is undergoing a slow metamorphosis. But into what? Lucas has only a very short time to discover the answer before he, too, undergoes...the change.
