At twenty-eight, Mandy Pajeck has spent most of her life taking care of others. Since the accident that took her younger brother's sight, Luke's complete reliance on Mandy's care has left both of them feeling trapped. But when Mandy meets handsome Zach Harrigan, she thinks she's found the ticket to her brother's happiness.

But when his life starts to feel empty, Zach decides to employ his skills as a horseman to train a mini guide horse for the blind--never expecting the project will lead him to beautiful, tender-hearted Mandy.

Even though she's charmed by Zach's patience and compassion, Mandy can't bring herself to fully trust him. And when Zach urges her to confront the truth about her mother's disappearance, the secrets they uncover are so shocking that even Zach's steadfast devotion may not be enough to win her heart...
