This Nordic Noir, part of a series by Swedish crime writer Camilla Lackberg, comes highly recommended to me. It drew my attention in part because of the eerie parallels between its plot and the increasingly odd abduction tale of sherri Papini. (And if you're fascinated by true crime, the chilling details of the "Emerald Triangle" and the many people who have gone missing there will fascinate you.) I can't wait to dive into The Ice Child.
That's also a stunning cover, isn't it? Great use of black and white with a slash of blood red.
