Over on the Tor books website, Alissa Burger has a column called Teen Horror Time Machine, which revisits YA horror fiction from back in the day. Her latest column looks at two snow-themed books: Slumber Party and Carol Ellis' The Window.
Beware spoilers, but the column is a good read.
In many ways, the pattern Pike establishes with Slumber Party, the first of the Point Horror novels, became the framework for much of the ‘90s teen horror that would follow, with themes of isolation, adolescent social drama, dark secrets that refuse to stay buried, and characters who aren’t exactly who they seem to be.
