Killing Floor by Lee Child
My introduction to Jack Reacher was reading 61 hours after hearing Lee Child speak at Bouchercon in 2010. After finishing the book, I had to find out what happened to Reacher and continued reading forward in the series. Once I reached the end, finally decided to go back to the beginning to read the book that started it all - Killing Floor.
Reacher finds himself in a big mess when he wanders in to a small town his brother had told him about, looking for history on a blind blues singer, Blind Blake. Within minutes of sitting down to eat breakfast in the local dinner, he is arrested for murder and things snowball from there. Imagine small town politics, town tough guys masquerading as do gooders, horrific murders, as well as a blooming attraction with Roscoe, the only female police detective as Reacher attempts to prove himself innocent. Six months out of the military and he's tough and doesn't back down for anyone. There are plenty of twists and turns while he tries to help the good guys expose and stop the bad guys. He has no qualms about ambushing the bad guys and taking them out anyway he can.
