When the call comes in, Detective Eira Sjoeden just can't say no. A body has been found locked in the basement of an abandoned house in the woods. Aside from the victim's name - which he carved into the wall before he died - the police have nothing to go on.

Eira is still struggling with the aftermath of her last big case - one that sent her own brother to prison for manslaughter, and left her ensnared in decades' worth of her community's secrets. But no one knows Adalen like Eira, and she soon begins to immerse herself in this eerie new case. Then, shockingly, someone close to Eira disappears.

Has he fallen victim to the same criminal they've been chasing? And can Eira put the pieces together in time to save him?
