And the perfect place for Cali Washington to run away from her past. But when a mysterious meteor crashes into one of the Moon’s cemeteries, Cali and her fellow Caretakers find themselves surrounded by a terrifying enemy force that outnumbers them more than a thousand to one. An enemy not hindered by the lack of air or warmth or sustenance. An enemy that is already dead.
