What he needs is someone to fix his broken horse. What he doesn't bargain for is losing his heart. In the wake of having his perfectly planned future ripped out from under him, Carter O'Sheen finds himself the unexpected, and somewhat reluctant, owner of a dressage horse with an expensive price tag. Not only does Carter know practically nothing about horses, D'Artagnan's surly behavior is making Carter's job of taking care of him more than a little difficult. Carter knows he needs help, but he doesn't know where to turn. The last training client Meg Beckett wants to take on is Carter O'Sheen, the heir to the famous O'Sheen Distillery. She's already got her hands full trying to keep Heart & Soul Ranch running and the bills paid. But when Carter reveals how desperate his situation is, Meg finds that she can't bring herself to turn him and his horse away. She agrees to take on D'Artagnan, promising herself that she won't fall for the horse's handsome owner in the process. But Carter and Meg soon discover that the situation surrounding D'Artagnan is more complicated, and more dangerous, than they first thought. Someone has it out for the horse, and they'll stop at nothing to get what they want. If they want to keep D'Artganan and the ranch safe, Meg and Carter will have to work together. But doing so might put something else they don't expect at risk: their hearts. Heart of Trust features a determined horse trainer heroine, a cinnamon roll millionaire hero, a touch of suspense, small town vibes, all the horses, and a low spice, closed door romance.
