When Garrett Sterling leaves for a horseback ride through his family’s sprawling Montana property, he’s expecting a relaxing break from the construction at the Sterling guest ranch. What he gets is something far more sinister. It all happens so fast that it’s hard for Garrett—and the authorities—to sort out the facts. Two things are certain, though: someone is dead and the killer knows there was a witness.

But when the one woman he could never forget emerges as a key suspect in the investigation, Garrett will do anything he can to help clear her name. She’s still keeping secrets from him—that much is clear. But Garrett won’t rest until he uncovers what really happened that day, how she’s involved—and why everything she’s ever told him is a lie.
