The Prodigal Wife by Susan Fox
Lainey and Gabe were married almost five years ago. In his will her father had a stipulation that she had to marry him. When her mother died her will stated she could get the inheritance if she stayed married to Gabe for five years. They never even spent a night together since they got married.
He's lived on the ranch and brought it back to what it was once known for. They spend a lot of time together on the ranch and get to know one another again.
