I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I just finished a re-listen of this. Aspects of it irk me - it bothers me when Charles confidently dismisses Anna's statement about not liking sex because he knows she'll enjoy sex with him, for example - and yet I like Anna and Charles' relationship in the first few entries in this series more than Mercy's various relationship options in the Mercy Thompson books.
Maybe at some point I'll actually write a full review for this. According to my records, I haven't yet, although I've listened to this (and previously read it) several times.
