Upon finishing this book I kind of want to curl up in a ball and stare at the wall for a while. The events that occurred throughout the books are disturbing and the breakneck speed of how it all came together left me uneasy at the end.
That being said, I think this is one of the best thrillers I have ever read. Not every book can deeply effect you mentally and make you shutter. This book does that. The characters are so much different then your typical crime/thriller characters. For one, this is a cast lead almost entirely by females and not your typical brave or delicate ones; these women have bite.
The crime/mystery parts of this book are ghastly but have all the pull of horrible tragedies we see broadcast on tv and can't help but follow out of curiosity on how something that horrible can happen. Clearly, those types of stories were a big influence on this novel (as well as in Gone Girl, I have yet to read Dark Places so can't say if that has the same media feel). Having read that the author worked for Entertainment Weekly, I can see why she wrote the story the way she did.
The portrayal of mental illness reminds me of what you see in Lars Von Tier movies (one of my favorite writers/directors). Actually come to think of it, he would be absolutely perfect for the direct of this movie. Hell, I could even see an aged Nicole Kidman being perfect as Adora.
I can't wait to read more from this author. I sincerely hope she has many more novels in the works.
