Reining in Trouble by Tyler Anne Snell

Guarded hearts. Unspeakable danger.

Detective Caleb Nash's childhood kidnapper has never been caught, and not even reuniting with his family has healed the scars. Then he meets guarded, beautiful Nina Drake. Damaged by her own past and living in self-imposed isolation, Nina tries to keep her distance from the cowboy lawman. But when she's the target of mysterious attacks, only Caleb can keep her safe. Will his vow to protect resurrect his own childhood torments?
