I'm pretty conflicted in my feelings about this entry into the series. As I stated in my review of the first book, it was a second reread months later that enamored me to the plot and some of the characters, after my lackluster initial reaction. 
 The Undoing opens right where The Unleashing left off, and we follow the Crows as they try to stop Gullveig, this time, with the Protectors, seeing as one of them, Ski Eriksen, is our narrator, Crow Jace Berisha's love interest. 
 As far as recaps of the previous events in series go, this wasn't the best one I've ever read - pretty bad, in fact - and is probably going to annoy both newbies and returnees alike. But once that was dispensed with, it settled into an interesting and satisfying plot that makes me want the next book now, because I want to know what's about to happen next. 
 Here's my quandary: I really enjoyed the events in this book, but it was a rough ride. I think it's fair to say I enjoyed the book despite itself. Jace, for me, was not a particularly interesting character in the previous book, and she isn't in her own book. To worsen matters, I found Ski and the Protectors to be exactly as annoying as the Ravens found them, and lackluster too. 
 What I did like about this book, is in the end what I liked about the previous book, despite my misgivings: the Crows, who are fascinating, most especially Erin and Chloe (OMG I hope Chloe gets her own book, or at least a novella); the Ravens; the overarching plot itself, and the shenanigans underfoot. Those kept me reading and keep me looking for the next in series. 
 If the final pages are anything to go by, the next book in series will be narrated from Erin Amsel's viewpoint, and what a treat that will be!
