Book #45 of 2016 (or something like that). 
 Even if you dislike horror, you cannot deny that Stephen King can truly craft a story. 11/22/63 is a hefty book (much like "Under the Dome"), and King uses that to his advantage. The plot meanders; it is not necessarily always as focused as you would find in other thrillers. However, that does not mean that there are portions that should be cut. Rather, I appreciate the leisurely pace of the book and the time spent on characters who may not matter all that much in the grand scheme of things. Was Miz Mimi an absolutely essential character? What about the four or so different bookies that Jake encountered? Probably not. But these pieces add realism to the story as we watch people float in and out of Jake's life much as they would in the real world. Plus, it helps us realize that there is so much at stake here-- Jake's mission affects everyone, not just those who make the news. 
 Prepare to read for a while, but you'll appreciate this read.
