A Past to Die for — Alysia S. Knight

Jana Hamilton starts running for her life the moment she sees her boss murdered and doesn't stop even after she's supposed to be safe in the hands of the U.S. Marshals. When one marshal is killed and another wounded, she's running again. She ends up in a small Wyoming town with an honorable sheriff who wants her out of his house. His nine-year-old son draws her in, while his Aunt plays matchmaker. Life would be a lot easier if she could remember things like her name and past, especially with a killer closing in.
