Pull down the safety bar and sit tight: you're in for a ride." --Ridley Pearson, author of the Kingdom Keepers seriesThe year is 2125 and the Magellan Science Academy has given two lucky cadets special Thulium tickets to join a team of space explorers on a time-travel mission twenty-four hours into the future. 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!
