Maggie Harrington is in way over her head running Matthews House, the shelter her famous sister Kate and brother-in-law Reid have opened to provide support to women and children in crisis. This job is just what Maggie needed after a disastrous episode in New York—or so she thought. The constant life-or-death challenges she encounters have her emotions on a rollercoaster of soaring highs and crushing lows. Living near her sisters Kate and Jill and taking regular rides on Kate’s beloved horse, Thunder, are the best parts of her new life. When Maggie hires Brayden Thomas to run an equine therapy program for the resident children, she does so knowing he's hiding something from his past. But his sterling professional reputation and qualifications have her taking a chance on the handsome horse whisperer who quickly becomes a friend and confidant. It doesn't hurt that he’s also smoking hot, funny, easy to talk to, and damned good at his job. It’s her first time being “the boss.” Surely she ought to maintain some semblance of professionalism when it comes to Brayden, right? But day by day, hour by hour, he makes himself essential to her and has her teetering on the fine line between personal and professional as her feelings for him intensify.
