One Girl. Two Horses. And a past itching to catch up. Fourteen-year-old, Colorado juvenile delinquent Mackenzie Lynn Stonebreaker doesn't do horses. But the volunteer gig at Hunter's Moon Ranch has its perks. With cold, hard cash she lifts from their boarding fund, Mac's poised for escape to search for her birth mom when an Arabian mare named Bella is viciously struck by a shotgun blast. Alive and talking-well, telepathically only to Mac-the horse begs for her help. Talking to horses totally freaks Mac out. But leaving Bella and her colt Raider isn't an option. Ditching her plans for now, Mac becomes a modern-day Dr. Doolittle, looking for justice. Only Mac tends to act first and ask questions later. When her protective instinct for the horses gets in the way of her good sense, Mac finds herself, once again, on the other side of the law. Dodging a return trip to juvie, thanks to the ranch owner's partner Dr. Rachel Hunter, Mac is now in the pediatrician's custody and living a life she could only dream. With newfound friendships, the gift of gab with two quirky horses, her first kiss, and a chance at that family she's always wanted, she can't quite let go of one thing. Abandoned and unloved by her mother, Mac wants to know why. But sleuthing for answers puts Mac on a collision course with the past-one that will shatter everything she believes in about herself and those she's come to love and trust at Hunter's Moon. Mac just may find that what she's been looking for her whole life is the exact opposite of what she will get.
