The Heir — Ann Jacobs

What should have been simple club play becomes complicated when lifelong neighbors Bye Caden and Karen Oakley discover there's more between them than one steamy night. But acting on their feelings is unthinkable, for if discovered, they could reignite a century-old feud between their families.
Sneaking around to be together ups the heat factor, but it's only a matter of time before the couple must come clean. Forever is hard to come by when one's father shoots first and asks questions later.
Against a larger-than-life ranch setting, the lovers must overcome not only their own misgivings, but the opposition of their respective families. A task that could prove to be as big as Texas.

THE HEIR is based on a book originally published as Lovers' Feud. It has been substantially revised in this new, updated version.
