Pike's Run, Texas, 1882

Andrew and Ben Lonnigan, brothers and private investigators, have accepted an important case—to reunite the long-lost DuBois daughters with their rightful inheritance. Abducted from their childhood home in New Orleans when they were three and two-years-old, Jo and Charlotte were adopted by separate families.

Andrew heads north to find Josephine Tatum—a pants-wearing, spitfire veterinarian who challenges his mind and captures his heart. Ben travels south to find Charlotte Ryan—the financial mind behind her father's ranch, with a sweet disposition and, unfortunately, a fiancé.

As the sisters journey toward destiny, Charlotte must guard her heart against Ben, a man too daring to ever return her love. And Andrew must hide his feelings from Jo, a woman determined to carve her own path. While the foursome battle feelings, they must also war with a villain from the sisters' past, one with the will and the means to destroy everything the DuBois daughters hold dear.
