Seventh grade didn’t end especially well for Jack, thanks to some hostile aliens. After the entire population of Earth's solar system is whisked away by alien technology, Jack and his classmates and teachers aboard the PSS 118 are the only humans left. But it’s a new school year aboard the new and improved PSS 118, and the public school spaceship is on a mission to find and rescue the rest of humanity from the evil Minister’s plans. If they can avoid the aliens hunting them down, steer clear of a robot civil war, and figure out who among them might be a traitor, Jack and his friends might just survive middle school. "Hilarious, high-stakes, un-put-downable fun."—Jarrett Lerner, author of the EngiNerds series "Another amazing trip across the galaxy with the students of PSS 118!"— Monica Tesler, author of the Bounders series
