I completely forgot about this book. Seriously, when I started reading it I couldn't remember a single thing other than I had an immediate need to read book 4 after finishing this one.
Definitely feels like the weakest in the series and reading Wrede's introduction (after I reread the book) I wasn't surprised to see that she was reluctant when writing this one.
If I were to do another reread of the series, I would start with book 4, read 1 and 2 and skip 3.
