Eleven-year-old George Mullin knows crazy when he sees it. Or at least he thinks he does. When his grandfather disappears and his grandmother tells the world that he was abducted my aliens, George is fairly certain that she has a screw loose...maybe several.

But all this changes when his younger brother Pete vanishes in the same way. George's grandmother is more than she appears, much more, especially when she reveals her underground space lab, complete with a functioning spaceship.

Is it time for George to come to his brother's rescue? You better believe it.
