Andrea Carter is finally pulling her own weight on the Circle C Ranch she loves. The only thing she loves more than helping to run the ranch is spending time racing and stunt-riding on her horse Shasta, with the help of wrangler Riley Prescott. Little does she know that when she and Riley stumble onto a mysterious cut in the fence around her brother's prize calves, life is about to get far more exciting--and dangerous.

A cryptic warning tied around a brick crashes through the window at a family party. Then cattle begin to die. When the horse barn catches fire, Andi knows this is more than just coincidence. But who is trying to hurt her family--and why? Evidence begins to point to criminals from her brother Justin's past who want revenge. But that discovery may be too late to keep Andi and her brother's family out of danger.

Now Riley is her only hope of rescue. Can he find her before she disappears from the Circle C forever? Can she keep everyone else safe until then?
