Peyton's Light (The Cambria Code #3)

Zoe never thought she’d be returning to Earth, yet only a few months after reaching Cambria, she and a small team are doing just that. Everyone who volunteers for her expedition knows Earth is likely swarming with the invaders, and it will take a miracle for their operation to be successful.

In the final book of The Cambria Code trilogy, Zoe comes full circle: she has returned to her home planet with the man who pursued her and convinced her to leave, and despite her initial reservations, she has loved him more deeply and fully than any man before.

Now, they are on a mission: they sent the Cambria code, and Zoe won’t abandon any survivors, even if nobody else believes she and Peyton can survive their final confrontation with the thieves of peace. But after landing on Earth, Zoe is forced to acknowledge they may be right after all.
