My rating: 4 of 5 starsA copy of The Waking Dark was provided to me by Netgalley/Knopf Books for Young Readers for review purposes.The killing day.The day the devil came to Oleander.That day.Oleander, Kansas is a small, quiet town that was never cause for much attention... until the killing day. The day when twelve people were killed in a few short hours by the hands of their friends and neighbors. Once all surrounding them were dead they then killed themselves having outlived their purpose. One survived to tell her tale, but she remembers nothing of the horrors that she dealt out. When the town is placed under quarantine after a horrific storm does further damage to the town, a darkness wakes in the citizens. The deacon decides this is the perfect opportunity to cleanse the town and the remaining citizens begin to take the law into their own hands. This book is insanity incarnate. It's dark and distressing. It's maddening and stupefying. It's one of the most horrific books I've ever read. It was fantastic. I have never been left more shocked and appalled by a single chapter and that's just what Robin Wasserman managed to do. The Waking Dark is horror, but it's not exactly scary. The madness that consumes this small town is more vexing and mortifying than anything and showcases perfectly the mentality of a small town and what can happen when it all goes wrong.The story is extremely character driven and is told from several different points of view with very distinct characters so it didn't cause any confusion as its fantastically written. It's a sordid tale told over the span of a few short weeks with enough violence to last a lifetime. The Waking Dark has drawn comparisons to Stephen King and Gillian Flynn, I believe for good reason. Having read both authors I feel that they both possess a subtle eeriness in their writing, a creepiness and unflinching details that sneaks up on you and takes you by surprise. I feel it must be said that this is one of the most violent and mature YA books I've read and is definitely not meant for a younger crowd. It involves infant murders, detailed meth use, crucifixion and people being burned at the stake (and that's not even half of the craziness that goes down in these pages). This is not for the faint of heart.There is so much to say about this story, but so much that needs to be experienced firsthand. I have to say though, I was extremely pleased at how the violence was maintained throughout the story because I figured it would letup at some point, (nope) but I expected it to end in a manner as shocking as the first chapter but it was a bit too tidy of an ending for my liking. Nevertheless, I am most impressed with this author and will be seeking out her past works.
