4. The 7 1/2 Lives of Evelyn Hardcastle

By Stuart Turton (458 pp)(ebook) This is a Groundhog's Day meets Agatha Christie -- a guy who needs to solve a mystery while re-living the same day in different hosts. It's set at this creepy, crumbling estate in the woods and everybody has a secret to hide or discover. Plus murder. It's definitely a page turner but I found myself getting taken out of the story wondering about the internal rules of the world.
