Sophia Sanchez is about to celebrate her sixteenth birthday, and she has no idea what the next year has in store for her! As the hero who saved Centauri Station from disaster, she is accepted into a prestigious starfighter pilot training program on Mars, and for the first time in her life, she will leave her beloved family and home behind for a distant planet millions of miles away.
Meanwhile, Tristan Crawford and his undercover comrades are still busy tracking down the masterminds behind the battle that nearly destroyed Sophia's home. As their investigation uncovers alarming details about who was behind the whole affair, Tristan sends his girlfriend Sophia a dire warning: Her beloved Centauri Station-as well as Kabooke, the wintry, tundra-like planet it orbits-may be in trouble again, as rumors of an even bigger leezhahi invasion begin to surface.
Can Sophia help stop an entire leezhahi fleet from invading the Kabookian solar system, especially when that fleet's vengeful commander Gwendiin has been harboring a personal vendetta against the very girl who defeated her the first time? No matter what happens next, Sophia is sure to have her work cut out for her in this new action-packed adventure!
