Rayna Kirkpatrick has lived her entire life with a secret: she possesses dangerous paranormal abilities. But she’s carefully kept her powers hidden from the world―or so she thinks. When new struggles in her life prompt her to seek information about her abilities, her internet search sends up red flags. Without her knowledge, she is placed under surveillance by a government team who monitors people with unique gifts like hers, individuals known as Trespassers. There are only two options for those manifesting such supernatural abilities: submit to regulation and scientific study or be eliminated.

Damon Hale is an invaluable asset to the government. As a Trespasser himself, he is perfectly positioned to determine how to handle others like him. When a series of unexplained deaths is connected to Rayna, Damon is assigned to go undercover to her California hometown to determine whether she’s the killer they suspect she is. As he gets to know this kind and charming woman, he’s determined to not allow his growing attraction to her to shake his objectivity. But the deaths surrounding her are no coincidence, and as his suspicions about her guilt begin to fade, he realizes he and Rayna must work together to discover the truth or risk becoming the next victims.
