Successful veterinarian Jessica Martin is on the verge of turning thirty. Still single and unmarried, she's beginning to worry that the strays she takes in are going to be the only children she'll get to care for. An odd twist of fate lands her at the feet of Cesario di Silvestri, bargaining away everything she owns in exchange for her father's freedom. What's Jessica to do when Cesario explains that the only thing he desires is an heir? She's always wanted children, but can she really survive a loveless marriage to this man who ignites a fire within her?
