"College student Riley Samuels, fresh out of a four-year relationship, accepts a last-minute invitation from her best friend, Lily, to visit the Atwood family’s vacation cabin in the remote, snow-covered mountains. Expecting Lily’s older brother, Caleb, to be absent, she is shocked to wake up in bed beside him—wearing his oversized sweater—three days after settling into his room. The lanky boy who once loved to tease her has grown into a powerfully built man with a dangerous aura and a knack for flirtation. Though Riley still claims to find him annoying, she cannot help but be captivated by his voice, scent, physique, gaze, and every move he makes as he draws closer to her.
After an earthquake triggers an avalanche, the cabin is buried under twenty-five to thirty feet of snow, cutting them off from the outside world. The struggle for survival draws them closer together. Caleb finally confesses that his childhood teasing wasn't born of dislike, but was a cowardly way to mask his secret crush on her. They officially become a couple, but as rescue is delayed and their firewood runs out, Riley begins to show signs of hypothermia. Caleb ventures out alone to seek help.
Riley was rescued, but Caleb was nowhere to be found. After days of agonizing suspense, the two finally reunited and acknowledged their true feelings for each other. A year later, they were married in the presence of family and friends."
