Aurora Rising

Aurora Rising by Amie Kaufman and Jay Kristoff is the first book in the Aurora Cycle series. It follows the formation of Squad 312, a ragtag group of cadets from the Aurora Academy, led by top recruit Tyler Jones. After a mission goes sideways, they rescue Aurora Jie-Lin O’Malley, a girl trapped in cryosleep for 200 years. Aurora may be the key to saving the universe, but they are all plunged into a dangerous and unpredictable adventure. With an ancient threat looming, the squad must come together to face challenges that will test their loyalty, skills, and courage.
