A man and woman must choose between family loyalty and heartfelt passions when they cross Boundary Lines from #1 New York Times bestselling author Nora Roberts.

The Barons and the Murdocks have shared a property line—and an animosity—in Montana country for generations. Jillian Baron has inherited her grandfather’s ranch but wants nothing to do with the longtime grudge between her family and the Murdocks. Then when Aaron Murdock gives her a most un-neighborly welcome, she becomes more than willing to defend the Baron name. Tempers rise between Jillian and Aaron, leading them to discover a shared kindred spirit and a growing love that will either heal both families—or drive them further apart.
