That’s a great question. I’m a huge Jack Reacher fan and I can definitely say that the best place to start is with the first book, Killing Floor (1997). It introduces you to Reacher right away and sets the tone for the whole series. Although each book can be read separately, but if you want to dive into the hero’s world and character development, it’s better to follow the order. By the way, if you want to know more about the whole series, I recommend you to look here: https://booksrun.com/blog/jack-reacher-books-overview/ . There’s a handy overview of all the books in order, and you’ll definitely be able to choose something to your liking. Reacher is the perfect hero for those who love edgy plots involving mystery and justice. He’s a former military policeman with a unique approach to problem solving, and that’s what makes his stories so compelling.
