A Million Suns by Beth Revis

Aboard the spaceship Godspeed, Amy has awakened to a world of turmoil. The cryogenically frozen passengers are still asleep, but the ship’s leader, Eldest, is dead—and Elder now faces the impossible task of governing a restless, divided population. As secrets buried in the ship’s past come to light, Amy and Elder uncover a series of cryptic clues left behind by their predecessor, leading them closer to the shocking truth about Godspeed’s mission. Love, betrayal, and rebellion ignite in the cold void of space as the two fight to uncover the final secret before it’s too late. A Million Suns continues the breathtaking Across the Universe trilogy with even higher stakes and deeper mysteries among the stars.
