So I can't really say if these are getting better or if I'm just getting used to the style and automatically skimming over the textbook parts.

I read this one in parts over several days and have read a few books since I finished this one, so I'm not recalling a ton of it. Did I guess all parts of the mystery? No. Was I surprised/shocked over any part? No. Was I annoyed with certain parts of minor story lines? Yes.

Will I continue the series? Yes
Will I reread the series in the future? Probably not. At this point, I don't see this as one I need to revisit.
