Fourteen miles east of Peachtree, Alabama, a secret is hidden.
The secret's name is Annabel Lee.

She doesn’t know why her enigmatic uncle has stowed her deep underground in a military-style bunker. He’s left her with a few German words, a barely controlled guard dog, and a single command: “Don’t open that door for anybody, you got it? Not even me.”

Miles away in Atlanta, private investigator Trudi Coffey is visited by a mysterious older man calling himself Dr. Smith. He’s been trailing a man for a decade — a man she met through her ex-partner Samuel Hill — and the trail has led him to her office. The last thing Trudi wants to do is to contact Samuel. But it will take both of them to unravel this mystery — before it’s too late.
