When eighteen-year-old Keller Hartman is recruited into the Legion’s most prestigious galactic unit, it’s a dream come true. He's worked hard for this. He’s ready to prove himself. The problem? His new partner—the beautiful, no-nonsense pilot Lament Bringer—wants nothing to do with him. Forced to work together under Legion orders, Keller and Lament team up with a motley crew of specialists to investigate a mysterious visionary who can predict catastrophes. As they begin to peel back layers, however, they realize there's more to the story than meets the eye. With threats mounting and secrets unfolding, Keller and Lament will need to trust one another in order to stop the dangers at play. But with trust comes other feelings—ones neither of them is prepared for. With the fate of the universe hanging in the balance, the only thing worse than failing their mission might just be losing each other.
