On a dark Alaska winter night, Annabeth Neilson is working late at her brand-new job, an animal rescue organization, when she is confronted by a gunman demanding something. What? She has no idea. Why? She has no idea. Though they never met, Malcolm Cooper steps in to help and it turns out the handsome man isn't just the man who saved her from a fate she cannot bring herself to consider, but is also her new boss.
Though grieving multiple losses over the past year, Cooper teams up with Annabeth to unravel the mystery of what the tall gunman was after. Instinct suggests things aren't what they seem at the humble non-profit but finding evidence of their theories proves nearly impossible. The trail of clues, scant as they are, takes the pair from the animal shelter to a remote Alaska town accessible only through a one-way tunnel that closes down each night, to a cabin in the woods and back again. They must get to the bottom of the gunman's demands before becoming victims of his bullets. Will Cooper's grief and Annabeth's guarded heart prevent them from uncovering the truth—and their feelings for each other—before it's too late?
