A stranded detective tries to solve a murder in a tiny Alaskan town where everyone winters in the same high-rise building, in this gripping debut by Academy Award–nominated screenwriter Iris Yamashita.

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 reasons for investigating the possible murder in this isolated place, which can be accessed only by a tunnel.

After an avalanche 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 a gang from a nearby reservation who are seeking shelter from the snowstorm.

Cara soon discovers that everyone in this town is keeping secrets. If there is anything as elusive as the residents themselves, it’s answers.
