Mallory Martin left her marriage and her unfulfilling job to move back to her hometown of Hillspring, Arkansas, and start a horse rescue. It's everything she's been missing, with paddocks of happy horses and one very quirky donkey. But when her cantankerous neighbor and longtime critic, Albert Cunningham, is found murdered in his fancy show barn, Mallory becomes suspect number one. Since Sheriff Grady Sullivan is ignoring all good sense and focusing only on Mallory, she decides to take matters into her own hands.

Aided by her best friend, Lanie, and rescue volunteer Tanner, Mallory races headlong into the investigation in search of the real killer. But horses and murder aren't the only thing on her mind when she meets Albert's handsome son, Braydon. Sparks fly, and soon she's got a new boyfriend. But there's a case to be solved, and she redoubles her efforts to learn the truth.

The suspects mount quickly. There's Albert's girlfriend, Kathleen, who was on the farm when he was murdered; organic farmer Heather Rogers, who accused Albert of contaminating her creek; and Philip Atwood, who'd been trying for a right-of-way across Albert's farm. None of the evidence is holding up though, and Mallory learns that she'll need to take the reins on this investigation if she's going to clear her own name.
