When Raine Tallentyre made the mistake of revealing her paranormal abilities, her most recent romantic relationship came to a hasty end. Her Aunt Vella, a gifted but troubled soul, had told her years ago to keep her talents a secret. And now that poor Aunt Vella-her last blood relative-has died, Raine has resigned herself to a lonely life.

But when she journeys to Shelbyville, Washington, to clear out Aunt Vella's house, Raine's highly developed sensitivity leads her to a horrifying discovery: a young woman bound and terrified in a basement storage locker. The victim has survived, but the culprit is still on the loose. Without warning, a new man enters Raine's life-investigator Zack Jones. Surprisingly, Zack isn't repelled by her powers: in fact, he has them himself. While Raine hears voices, Zack sees visions and within hours of their meeting, Raine experiences an intense, thrilling intimacy- mental, emotional, and physical-she never dared to expect.

There's one complication, however: Zack Jones is working for the Arcane Society. This secret organization, dedicated to the study of paranormal phenomena, shattered Raine's family with an act of betrayal long ago, and she's not about to trust them now. But as a killer makes her his target, and a cabal of psychic criminals known as Nightshade operates in the shadows surrounding them, Raine and Zack must rely not only on their powerful abilities but on each other . . .
