A Spinster to Reform the Duke by Tiffany Baton

Perhaps a wounded heart is not beyond repair after all…

Rebecca is an heiress. Something she realized is both a blessing and a curse, when she found out that her former betrothed only wanted her for her wealth. After getting her heart broken, she vowed to stay away from anything having to do with marriage. Most of all eligible, dashing dukes.
Timothy Fletcher is ready to settle down. He is in search of an obedient bride of convenience, one he would not have to explain his whereabouts to, or have her meddle in his affairs. So why is Lady Rebecca, a very outspoken spinster, the one haunting his dreams?
As their initial disdain turns into something more, Rebecca must decide whether she can trust Timothy with her carefully-guarded heart. And Timothy must decide if this spinster might be worth changing for.
