He's a one-night charmer, playing for now — but she's playing for keeps.

Karlie Kyle has had it bad for Luke McKade since she was a shy ten-year-old in braided pigtails. Back then, she didn't have the courage to follow through on her crush. But now that she's all grown up, she's ready to stake her claim and brand the heart of the sexy, smooth-talking cowboy who "can't be tamed."

And lucky for Karlie, her new career is about to throw her right in his path again.

Luke doesn't do commitment, but when Karlie shows up to intern on his family's ranch—with dangerous new curves and a tempting proposition he just can't refuse—it's clear she isn't the same girl he grew up with.

Deep down, Luke knows the responsible thing to do is keep their relationship strictly professional. But with every secret encounter, he quickly finds Karlie's got a way of getting him to do things he swore he'd never do…

As their summer agreement heats up, the broken rules start to multiply until their casual fling threatens to move into uncharted territory. But when big dreams come knocking, can small-town love compete?
