Holiday in the Hamptons by Sarah Morgan

Toward the end of New York, Actually, we learned that Felicity Knight had an ex-husband who had turned up in Manhattan. Felicity had married Seth Carlyle when they were both too young and divorced him soon after. She has tried to face the sexy vet but has been unable to do so. Instead, she grabs the chance to leave town and head to the Hamptons when her grandmother calls for help.
Unfortunately, (at least in Fliss's eyes) Seth was only in Manhattan for a short stint before he returned to the Hamptons where he immediately runs into Fliss who panics and claims to be her twin sister.
Seth still has feelings for Fliss and is delighted to have this chance to get to know her now. If only she'd cooperate...
And, ufda, was Seth a totally bland bulldozer. We know nothing about him except that he seems to be an all-forgiving saint who doesn't want to give up on their love. He's not an alpha-hole because he does give Fliss a little bit of space but other than the fact that he's missing his father, we really don't get to know him. Nor does he have any discernible flaws while Fliss is described as being just riddled with them (and not just in her own head). At the end, I'm really not sure that these two people are getting an HEA.
I am hoping for better in the next book because I know that Morgan can write in-depth characters and fun-to-read books.
