Charlotte Whitaker only wanted to survive Christmas without embarrassing herself in front of her ex...and his shiny new fiancée. But thanks to her meddling little sister blurting out that Charlotte's already dating someone, she's now stuck bringing a plus-one who doesn't exist. Enter Sebastian Montgomery-cocky, gorgeous, and the man Charlotte spent one unforgettable night with. He's also her brand-new coworker, which makes their chemistry inconvenient at best and explosive at worst. When he accepts to play the role of doting boyfriend for her family's holiday getaway, Charlotte knows it's a terrible idea. Now they're tangled up in every Whitaker family tradition-competitive cookie decorating, awkward mistletoe moments, and Charlotte (a world-class skier in her own mind) swallowing her pride as Sebastian insists she try snowboarding...and face-plants spectacularly every time. Every lingering touch and stolen kiss threatens to burn through their careful boundaries. And the more they pretend, the harder it is to remember why this was supposed to be just an act. Charlotte wants to save face. Sebastian wants another taste. But with family watching and sparks flying, they might not make it to Christmas without breaking every rule.
