Well the series started with one POV, then got more, and more and well this last book has like 8 different POV's (too many in my humble opinion) I found that some of the action was left do be desired, and not in a good way when we were constantly shifting from one person to another, from one small amount of "action" to rather trivial things.
What was happening to most of the characters for the most part was boring, I wanted to stay in Zoey's head and maybe at the most Stevie Rae's because they had the most to say. The other characters either just seemed to whine or in the case of Stark be more concerned about sex. The main conflict was a little drowned out.
Then at the very end, I was actually hoping that the series was going to be done with, PC decided to add some really rather crazy things that in my mind means that the series won't be coming to a close anytime soon.
Oh and to why I will still will buy the next book. It's a quirk of mine, I cannot just toss a series or any book a side, I have to always, always see how it ends, not matter how much I grow to dislike it.
