Kate Miller has worked hard to carve out a secure job at the Mustang River Ranch. The horrors she faced leading a mountain rescue attempt are firmly buried and she's content guiding sedate trail rides and instructing children in basic survival skills. There's no room in her life for anything that could threaten her newly found serenity.

Former SEAL Jack Becker is hot enough to melt any woman's cool exterior. But his arrival coincides with the presence of a horse-loving teenager and her suspiciously well-armed bodyguards. Jack's mission is always his priority but despite simmering suspicions, his attraction to Kate is impossible to ignore.

But someone with sinister intentions is lurking. And when a simple trail ride to see the wild mustangs takes a shocking twist, both Kate and Jack will do whatever necessary to save the President's daughter. Can they work together to save her, or will any of them leave the mountain alive?
