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 humans 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 to him 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.
