I'm about a quarter of the way through Doctor Sleep, after getting it earlier today. It's not bad so far. But is it me, or does King take a very long time to get to the horror in all his books? Okay, he has a few tidbits here and there, like the prologue for this book, but he takes a while to get to the actual main horror. For example, he's already introduced the main villains of Doctor Sleep, the True Knot (a sort of vampire commune that feeds off the Shining rather than blood), but he's yet to show them doing anything really villainous yet.
