It's fine - damning with faint praise, I know - because it's really just middle of the road. Predictable plot/mystery and fairly thin character development for anyone. Lots of recapping events and situations, both from the first book as well as the current one. I ended up listening to this at 1.5x speed and heard lots of repeated phrasing, which made this feel more tedious.

Also, Aunt Millie is a terrible character - not nearly as charming as the author thinks.
