The Goblin King - Shona Husk
Expect the unexpected when you read Shona Husk's books. You'd think I'd have learned that with "Dark Vow" which is one of my favourite almost-steampunk stories. She doesn't allow her characters an easy out, and she definitely presents them (and readers) with unexpected challenges.

The Goblin King is as sexy as its cover. It's paranormal romance that weaves in Celtic/Roman history, contemporary issues and a vivid fantasy landscape. All that and a hero to swoon for.
