Possible spoilers ahead for Mr. Mercedes and/or Finders Keepers. 
 I enjoyed this one, although I think it was my least favorite of the three. The biggest reason being there is very little Jerome present, and he was one of my favorite characters. The reason for his absence is perfectly rational, but damn I really missed him in End of Watch and Finder's Keepers. 
 The genre of this book is also more classic horror then it is even trying to be a mystery. I'm not really sure I'd classify the first two novels as mystery either. Sure there is detective work happening but the reader knows whodunnit from the start so to me it kind of mostly just seems like horror. This isn't meant as a critique in anyway- I like horror. I just think these novels sometimes caught a bad rap because they were advertised as mystery/thriller (there may be an argument for thriller) but there wasn't much mystery in it for the reader. 
 I also felt like there was some of the King writing style missing from this one. When I think of Mr. Mercedes I think of that first letter Hartsfield sent to Hodges. I think of the maniacal style, the randomly capitalized words. I think of the seat cushion with the words ASS PARKING written on them and the cheesy boy band, 'Round Here lyrics "Kisses on the Midway". I felt like some of those finely tuned details were missing from End of Watch. 
 Overall, it was an exciting read with some interesting concepts at play. It was a fitting and definite conclusion to the trilogy. 
 But, MAJOR SPOILER:(view spoiler)[I'm really upset that Hodges went out by way of pancreatic cancer! *sobs* I feel empty inside. This was not the way Det-Ret. Hodges was supposed to go. I feel betrayed. I feel like Morris Bellamy after reading The Runner Slows Down. Couldn't they have all just ridden off into the sunset together?? Brady's death though, now that was poetic justice. 
 But, Hodges! If the show makes it that long, and they stick to the books, I will definitely not be able to watch all the way to the end. I'm pretty heartbroken. The tombstone reading "End of Watch" was a kick in the gut. I knew from the beginning it wouldn't end well but I was hoping for Hodges to go out in a blaze of glory. Trap Brady in his head or something and then sacrifice himself. That's grim- I know. But the thought of him laid up in a hospital for 8 months really hurts. I'm sure I'm missing the point there, but I reserve the right to not like it. (hide spoiler)]
