The Christmas Bet by Meg Easton

Neither of them is looking for love this Christmas.
Their six-year-olds have other plans.

Rachel Meadows has her dream job, a new lease on life after beating cancer last year, and extensive plans to make this the most merry, bright, and wonderful time of the year for her six-year-old son since she missed so much of it last Christmas. But all her carefully crafted plans fly off faster than a reindeer-pulled sleigh when her coworkers challenge her to a bet—say yes to every holly jolly and not-so-holly jolly thing that comes her way. Except there’s one thing she never expected to say yes to—meeting Nick.

Nick Stewart just moved to the small town of Mountain Springs, Colorado, hoping for some stockings, snow, and faces all aglow—but mostly a fresh start for him and his six-year-old daughter after losing his wife the year before. His late wife didn’t want him to wait long before remarrying, but he loved her with all his heart and isn’t sure he’s ready to jingle all the way to the world of dating again.

When Rachel’s son begs for help with his school Christmas program and Nick’s daughter asks for the same, both parents say yes. Neither of the two little first-grade enemies ever guessed that their begging would lead to their parents meeting—or that their competitiveness would turn into cooperation for what has become Operation: Christmas Matchmaker. Six-year-old style, of course.
