When Diana Greene leaves her hometown for a new life, she thinks she has left the past behind: her sister's disappearance, her mother's illness, and the visions Diana used to see...a clearing in the woods...a moonlit night...and human bones buried in the ground.

And her past remains dormant until the day a mysterious woman appears on Diana's doorstep, promising Diana something she can't resist.

"If you help me find my missing daughter, I'll tell you what happened to your sister."

Soon Diana is digging into the past, uncovering secrets the town has long since buried, secrets that the powerful wish would stay hidden. But when another girl disappears and the visions return to Diana with a vengeance, she knows she is on the brink of solving more than just a few missing person's cases. She is on the brink of discovering the dark and violent covenant that the town itself was founded upon.
