"Beautifully illustrated, wonderfully crafted, the story leaps from the pages faster than you can turn them. Pull down the safety bar and sit tight: you're in for a ride." --Ridley Pearson, author of the Kingdom Keepers series

But when their mission goes wrong, the two kids must band together with a tiny flying saucer sidekick to save themselves, their crew, and all of Space Mountain--before time runs out and the galaxy is destroyed!
