After the death of her father, Roxanne leaves Boston and returns to the family ranch in Texas. Still mourning and trying to readjust to life on the ranch, her nightmares of the mysterious black rock return. Life for Roxanne becomes even more confusing when she meets sexy neighbor, Collin O’Neal. Despite being the rudest man she’s ever met and his fear of commitment, Collin can turn her brain to mush and set her soul afire with just a look. While struggling to remain the lady she was raised to be, Roxanne must deal with another man trying to stake his claim. Bradford Wellman is handsome, charming, and obsessed with making her his bride. Unknown to Roxanne, both Brad and Collin have reasons other than romance for getting close to her.
