Status Updates From Under an Enchantment

I'm not sure I like this "hero" at all. I'm going to take revenge on these three people by seducing and abandoning a woman who has nothing to do with the wrong they committed. This is definitely going on the "male lead asshattery" shelf.

Is Malcolm a selkie? He walked right out of the sea.
Historical, set on a small island, near Scotland I think.
She pretends she is daft, to avoid marriage, but she is rather fey, like a changeling in a nest of vipers.

Interesting...I've never read a book where the hero is thought to be a Selkie (seal in the water/man on land)! If anyone can pull this off...my money's on this author!
