When Harper Lee Crockett returns home to Paradise Ranch, Wyoming, the last thing she expects is to fall head-over-heels in lust for Cole, childhood neighbor and her older sister's long-time boyfriend. The spirited and artistic Crockett sister has finally learned to resist her craziest impulses, but this latest trip home and Cole's rough-and-tough appeal might be too much for her fading self-control.

Cole Wainwright has long been fascinated by the sister who's always stood out from the crowd. His relationship with Amelia, the eldest Crockett sister, isn't as perfect as it seems, and with Harper back in town, he sees everything he's been missing. Cole knows they have no future together—he's tied to the land and she's created a successful life in the big city—but neither of them can escape their growing attraction or inconvenient feelings.

As Harper struggles to come to grips with new family responsibilities and her forbidden feelings for Cole, she must decide whether to listen to her head or to give her heart what it wants.
