When I first picked up The Unleashing, I was thrown a bit by the dynamic in the Crow house. All the women with their varying degrees of, lets face it, craziness took a bit for me to get used to. I was happy that I stuck the first book out, because once I understood the ebb and flow of the other women's personalities the humor of the situations really came to the forefront. 
 That same humor flows into the second book The Undoing. I think just by understanding the writing style and the characters, I ended up enjoying The Undoing even more than the first book. I found the antics between the Crows even more funny. I loved the somewhat naive seriousness of The Protectors. Their love of books was charming and the way they thought themselves smarter than other clans was hilarious. 
 Jace was a stand-out Crow for me in The Unleashing. Her penchant for hiding in seemingly random places was intriguing. I wondered what her deal was, in a good way I assure you. So I loved the The Undoing was her book. What I loved even more was that her quirkiness was not a result of her tragic past the lead to her becoming a Crow. That kind of closed off manner that she has is just the way she is, and I liked that the point of this book wasn't trying to "change" who Jace was. Yes, there are some characters who don't understand Jace and want to get her out of her shell, but the core group of people who matter to Jace and who care about Jace in turn would never think of changing her. 
 Ski was a great love interest for Jace because he sought to understand her so he could fit into her life rather than trying to make him fit into hers. There was attraction between the two of them from the beginning but because of Jace's past experience with her ex she's hesitant to start anything with anyone. I loved that there was really no pressure on either side for something to happen, things just developed naturally. 
 I'd say that it's probably wise to read the first book in the series before jumping into this one just because one of the main story arcs from the first book flows over to The Undoing. I think readers are well aware at the end of the first book that things are not yet taken care of, even if the characters aren't so aware yet. The same thing happens in this book. There are definite story threads that are dealt with yet no necessarily completely resolved but I will go so far as to say there's nothing cliffhanger-like about the ending by any means. 
 Overall, this has started to be a series that I really look forward to. There's just the right amount of humor coupled with some very interesting Norse mythology. I liked seeing Kera and Vig from the first book still get a good amount of page time, yet we see them from Jace and Ski's points of view and it's always interesting kind of turning the tables in how a character is perceived. This series is highly recommended. Plus, there's a not-to-be-missed party at the Crow house!
