A Red-Rose Chain (October Daye, #9)
by Seanan McGuire
Good, but the previous book was a tough act to follow. And we still don't know WTF is up with the false queen, sigh. (And now I'm rereading the previous book, because I needed to.)
Walther went from being one of my favorite underused characters to one of my even more favorite characters who got a whole big plotline of his own. <3!!
