Wildlife biologist Evangeline Beaumont has already photographed an illegal bear trap and shot a poacher's rifle out of his hands when Forest Service officer Jonah Cooper finds her pinned down in Devil's Canyon.
A single kiss from a decade ago still hangs between them, and the distance Jonah kept never stopped him from wanting her.
Two armed men are hunting the evidence on her camera while a spring blizzard seals every trail off the mountain.
Forced together in a remote line shack, with one bed and years of unspoken longing between them, neither can keep pretending the old wound has healed.
Evangeline refuses another no, and Jonah can no longer tell himself that watching over her from afar is protection enough.
As the poachers close in, getting through the night means trusting each other completely.
