The Reluctant Wife by Bronwen Evans

Abby Taylor walked out on her irresistible husband three years ago. Now she has no choice but to return to Italy to ask him for a favor. To pay for her grandmother’s heart operation she needs his money, but it comes with strings attached.
Conte Dante Lombardi has it all–an Italian villa, a successful family business, and a noble title. But he needs a child to carry on his legacy and time is running out. He also hopes to satisfy the desire Abby rouses in him. As Abby uncovers why he’s in such a hurry for a child, she falls in love with him again … just as she realizes it might be impossible to keep her end of the deal.
