Fair warning: once you’ve read it, you can’t unread it. Karin Slaughter’s latest novel Pretty Girls snatches the genre of psychological suspense and infuses it with gritty descriptions that nearly froze my face in a mask of shocked surprise. I’m not squeamish—I’m an ER doctor—but weeks later, I’m still perspiring and fluttering my hands at the thought of it. But if you like a bit of horror in your novels, this might be the book for you. Slaughter is a master storyteller. Indi
