Changing the Rules (Champion Valley #3)
Erin Kern

Cameron Shaw knows exactly what he's doing when it comes to coaching high school boys on the football field, but caring for a six-year-old girl is a whole different ballgame. When a gorgeous, highly opinionated woman shows up with his niece in tow and claims he's Piper's new guardian, Cameron's first response is "hell no." But he can't abandon a little girl who just lost her mother....
Audrey Bennett wasn't planning to stick around town, but Piper's gruff, way-too-good-looking-for-his-own-ego uncle clearly needs help. The longer she stays-watching Cameron teach Piper to make pancakes and tie her sparkly pink shoelaces-the harder it is to leave. Especially when he stops arguing and gives Audrey the most toe-curling kiss of her life. But just as she thinks he might be the one, a secret he's been keeping threatens to tear apart their happy little family.
