Do the books get better after this? I read the one before this which was decent. This one is, to put it bluntly, pretty bad. Endless chapters of the same crap in the caves over and over again. It's not scary, it's annoying. Beyond annoying.

More generally, the same structure/formula also seems to have been followed as in the previous novel but has way less characters to care about. I'm almost not able to finish this one, it's so bad. Is this how the rest of them are in general or is this one an odd one out?
