When a mysterious spaceship appears above Cambria, Zoe remains skeptical that it’s anything but an elaborate hoax. By the time the first spaceship is joined by two others, Zoe reluctantly admits that Earth has been invaded, even though it’s a pretty lame invasion: the aliens look remarkably human and keep to themselves. From what reporters are able to learn about them, they seem incredibly arrogant and boring anyway. After meeting Peyton, one of Earth’s newest residents, Zoe feels an immediate attraction although she is reluctant to become involved with someone who isn’t even human. But she soon discovers that these aliens are far more dangerous than they’ve led everyone to believe, and the secrets they are hiding may signal the destruction of her entire planet.

After landing on Cambria, Zoe realizes she can’t spend the rest of her life as the source of a rivalry between the two men she loves, so she volunteers for Peyton’s army, which threatens her relationship with Adrian. But after five months of fighting the darkness that has repeatedly tried to drown her, she needs her own justification for escaping an invasion few humans survived. Protecting those who are left gives Zoe a new sense of purpose, but she is quickly confronted with the realities of what took place on Cambria when this planet was invaded, and she will soon discover if she is capable of being the savior of her people she desperately wants to become.

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.

Twenty years after the arrival of the thieves of peace, the surviving invaders are again threatening the lives of everyone on Cambria. But this time, it’s Zoe and Peyton’s daughter who will lead the expedition to save everyone again. Jenna has heard “like mother like daughter” her entire life. She’s always had to walk in her mother’s shadow, and she’s grown tired of everyone expecting her to be Zoe Arren. But when the thieves of peace who’d been left behind on Cambria begin looking for new food sources, Jenna decides to confront them, and she will have to discover if she’s really just like her mother after all.

Discovering we're not alone in the universe can be a blessing and a curse. When a mysterious spaceship appears above Cambria, Zoe remains skeptical that it’s anything but an elaborate hoax.
