The Captain's Kid — Liz Coley

Whenever his parents went out on missions for the Space Survey Corps, Brandon Webb was left behind on Luna, left to dream of journeying between the stars, meeting aliens, defeating villains, saving the world. Now it's his turn for adventure, permitted at last by the captain, his father, to join a year-long trip to a failing colonial planet on an emergency resupply run. Or so he's told. Brandon's former dreams could turn to nightmares when the starship is sabotaged, the alien holds secrets about his past, the villain is on the right side, and the world isn't ready to be saved.
