I liked them okay, but I'm the kind of reader who can skim a boring part and then re-engage when something interesting happens. The torture is easy enough to skim over. It's creepy and monotonous but I've read worse

My biggest problem is that they appear to be written for people with no memory- each book spends more and more time summarizing the previous books but again I skim those parts.

There is some truly great story and some well developed secondary characters hiding in there if you're willing to search for it, and there's a lot of dreck to slog through while you're searching.

Get one from the library and see if you like it, if you don't, take it back
