Loved this book, but since it's been two years since the release of the last one, I had to reread the series to get myself back up to speed (nice to have everything in my kindle archive!). I loved the developing story of Cassie's life as the Pythia, but like many other reviewers, I found the action scenes a little too frenetic. I would have preferred less action, more backstory.
What I did really enjoy was learning more about Cassie's parents, and more about Mircea's and Pritkin's families. I enjoy watching Cassie try to figure out her love life, but there was some information divulged about Pritkin, and the deal that he made with his father, that made me really upset, but I think I figured out the loophole at the end, so I think I am going to be okay with it.
