Gr 3–7—Teens Gabriel, Misty, and Braden are aboard a ship headed to Mars when things begin to go horribly wrong. Because of overcrowding, Earth's residents have been forced to join a colony on Mars. When the ship malfunctions and the adults on board die, the three teens become responsible for landing the ship safely. Each book outlines a problem that needs to be solved before they successfully land on the far-away planet, including a fellow teen who sabotages the mission and an explosion they need to create to put the ship back on course. Because of the short length, each book feels more like chapters of a larger book and thus won't work as a stand-alone. With big, readable text and bold use of font on each page, the titles are highly readable, with visually pleasing retro futuristic illustrations. VERDICT The series is written at a second grade reading level and will be of interest to fans of science fiction and action.
