I hadn't realized that this was an unrequited love story when I picked it up. That trope rarely works for me, and the heroine had been in love with the hero for 15 years, whom she hadn't seen in all that time, so this one never stood a chance.I had a few other problems with this story. The reason for the marriage/engagement of convenience was weak. There was an evil ex-wife used to make the heroine look better in the hero's eyes. And in the end, I didn't believe he loved he, really. He went from liking that the sex (all fade to black, btw) was good and she was good with his kids and she took care of him to the leap that he was in love, though I never saw that development on the page.
