****UPDATE: (04/08/2017)*** 
 DISCLAIMER: This is the book is very problematic. I know this book is problematic. I am warning you of this before I go any further into my review. DO NOT READ this book if suicide or racism is at all triggering for you as this series heavily relies on both as plot devices. Mr. Mercedes is not a book I recommend to many people. It is very dark. It deals with a serial killer, racism* (including racial slurs), fatphobia, incest, suicide, and more. 
 *There is always the problem of a white author writing about racism. So be forewarned that King has a racist main character whose racist POVs aren't called out. 
 Actual Review: (originally posted 11/01/2015) 
 I listened to the audiobook narrated by Will Patton so this review will discuss his narration as well as the book itself. 
 Holy. Fucking. Shit. This book. Just...wow. This book. I just--it was so fucking good!!!! King wrote an incredibly addictive, suspenseful, creepy book. Mr. Mercedes is not meant for the faint of heart. 
 The book is written in third person and told primarily from two points of view: the retired Detective Hodges, and Brady Hartfield aka the infamous Mercedes Killer. Both points of view were written flawlessly about complex characters. It was really interesting to hear the story from the perspective of the killer and the man trying to catch the killer. Plus, Will Patton (my audiobook narrator) did an amazing job of changing the pitch and tempo depending on which POV he was reading. So Patton was a huge reason why I loved this book so much. 
 Brady's POV is creepy and totally fucked up. There were many times listening to the audiobook where I would wonder what the fuck did I just hear!?! 
 Brady is a terrible man who is incredibly racist, fatphobic, homophobic, and has incestual thoughts about his mother. His chapters were incredibly uncomfortable to listen to. He uses the n-word frequently, talks about how his mother "relieves" his headaches, and is the crudest, rudest, most bigoted POV I've ever read/listened to. But yet, King is able to write Brady in such a way that kept me interested the whole time. 
 The amount of times I thought oh, shit! and no, no, no! while reading this book were unreal. I wasn't bored for a single moment listening to Mr. Mercedes. The book was fast-paced a full of suspense until the very end. 
 As long as the content isn't triggering for you and you aren't squeamish about creepy thrillers, then I 100% recommend this book to you. I look forward to reading (or listening) to the sequel.
