She just wanted a dream vacation. He never expected to be part of the plan. Nora's been stuck in the same routine for far too long—work, home, repeat. When she spots an all-expenses-paid cruise giveaway, she decides it's her chance to finally break out and see the world. There's just one problem: the contest is for couples only. Enter Sam Reed, her best friend's older brother, a dependable firefighter… and a single dad with zero interest in romantic complications. Convincing him to pose as her "other half" is a long shot, but Nora's nothing if not determined. One fake marriage license later, they're sharing couple selfies, cozy dinners, and enough playful banter to fool anyone watching. But spending time together stirs up feelings neither of them planned on—especially when Sam's daughter starts looking at Nora like she's already part of the family. What started as a ticket to tropical sunsets and umbrella drinks begins to look a lot like something worth keeping. And when the contest ends, they'll have to decide if their happily-ever-after ends too… or if this was just the beginning. A Fake Marriage to My Best Friend's Fireman Brother is a swoony, slow-burn romance with fake-dating fun, small-town charm, and a single dad hero who might just be the real prize.
