If like me you read a lot of spooky story collections, you will come across the same stories every so often. But it's okay. If you're like me and don't have the best memory for the plot points of what you've read years before, it's almost like reading it for the first time with a slight sense of deja vu. Nightshade is a solid collection of "ghost" stories from "classic" writers of the 20th century, so... Joyce Carol Oates, Shirley Jackson, Franz Kafka, etc., and as such it provides a lot of variety concerning what is or is not a ghost, and it has a lot of slow burns, and that's why it's a successful collection, if you're like me.
