Refuge by Lisa Tawn Bergren (The Full Circle Series, Book 1) by Books In Motion.com

Will the danger that stalks them destroy their life together before it begins? When Rachel dared Beth to answer a personal ad in The Ranchers Journal, she never thought her citified friend would become a bona fide rancher's wife. Now Rachel, too, is falling in love with the glorious valley and Dirk Tanner, a rugged rancher who makes it his home. Rachel isn't the only San Fransiscan drawn to Elk Horn Valley. Jake, son of a San Fransisco client, has taken a shine to it too, and to Emily. Will threats from the present destroy any possible future for the couples?
