On a frigid February day, Anchorage Detective Cara Kennedy stands by the graves of her husband and son, watching as their caskets are raised from the earth. It feels sacrilegious, but she has no choice. Aaron and Dylan disappeared on a hike a year ago, their bones eventually found and buried. But shocking clues have emerged that foul play was involved, potentially connecting them to a string of other deaths and disappearances. Somehow tied to the mystery is Mia Upash, who grew up in an isolated village called Unity, a community of women and children in hiding from abusive men. Mia never imagined the trouble she would find herself in when she left home to live in Man’s World. Although she remains haunted by the tragedy of what happened to the man and the boy in the woods, she has her own reasons for keeping quiet.

When a local teenager discovers a severed hand and foot washed up on the shore of the small town of Point Mettier, Alaska, Cara Kennedy is on the case. A detective from Anchorage, she has her own motives for investigating the possible murder in this isolated place, which can be accessed only by a tunnel. After a blizzard causes the tunnel to close indefinitely, Cara is stuck among the odd and suspicious residents of the town --- all 205 of whom live in the same high-rise building and are as icy as the weather. Cara teams up with Point Mettier police officer Joe Barkowski, but before long the investigation is upended by fearsome gang members from a nearby native village. Haunted by her past, Cara soon discovers that everyone in this town has something to hide.
