If you liked 11.22.63 (I know how silly it is to preface a post like this on this site), then the genre of alternate history may be interesting to you. The master of this genre, in my mind, is Harry Turtledove. It was interesting to see how Jake/George kept proclaiming that he had been an English major, instead of a history major in 11.22.63, which mirrors Stephen King's academic bona fides of course. Well, Harry Turtledove is a PhD in history, and his works are also very engaging. He builds some fictional characters, as well as real characters from the history books and brings them to life (in my humble opinion). The Guns of the South is a fun read where the Confederacy's luck changes late in 1864 with the help of some "sympathetic" time travelers from the early 21st century. How Few Remain sort of does it with a different take. Turtledove may be known for some of his fantasy stuff, but I haven't ready any of that.
