Kendall King's world is shattering. Abandoned by her husband and stripped of her finances, the single mother of a 13-year-old daughter faces imminent homelessness. Her only solution is a heartbreaking sacrifice: enlist in the Army, leaving her daughter with a neighbor while she goes to basic training. But basic training brings more than discipline. Stumbling upon a strange, half-buried object, Kendall is struck by a dot of light-an alien from outer space. Naming him Kal-El, her personal superhero is born. A far greater threat looms than Kendall's shattered life. A planet has exploded, sending massive, world-ending boulders hurtling toward Earth. An elite team of astronauts and space experts is assembled for a desperate mission to stop them. Their one crucial need? A gunner good enough to hit every target. That person is Kendall. Saddled with the fate of humanity, Kendall must now juggle saving the world, inspiring her daughter to stay focused on her schoolwork, and navigating the unexpected, very welcome distraction of the mission leader. Can a single mother who sacrificed everything find the power within herself to save the entire planet?
