Beautiful and haunting

I've always loved stories about shapeshifters, and the folklore and mythology of Scotland - I used to wish I was a selkie as a wee girl on holidays up north. These retellings give the women fairer endings, deserved revenge, and justice. There were stories that were familiar, and some I'd never heard. It's early in the year but this is a contender for my favourite book of the year. I'll definitely be buying a hard copy of it to reread.
