Title: The Accident Season
Author: Moïra Fowley-Doyle
Every fall, Cara's family becomes strangely, dangerously accident-prone for 4 weeks. They suffer through bruises, broken bones, and worse. But why?
The Accident Season is seriously creepy. Early on, Cara notices that Elise, an old friend from school, is in all of her photos. ALL OF THEM. Vacation photos, family snapshots - everything. The more you think about that, the CREEPIER IT GETS.
It's also atmospheric as fuck. The writing is haunting, and will give you that prickly "OMG I AM PRETTY SURE MY HOUSE IS HAUNTED" feeling.
I was worried this would resolve with "Oh it's all in the child's imagination," which is a fucking lazy plot device. This book has a much more satisfactory resolution. It's both creepy and sad, but also just a bit reliant on cliché.
Totally worth a read, but you may want to wait for the paperback or get it at the Library (link is to Amazon for those who lack patience).
Full disclosure: I bought it with my own hard-earned cash.
