On one hand, it’s over. It’s a solid series with a lot of interesting world building that kept me turning pages right up to the end and managed to wrap up a surprising number of plotlines up into a huge final battle. If that’s all you’re looking for and you’ve already read the first two books, go ahead and read this one. It’s the first two books, only bigger.
On the other hand, I still don’t like Kylar. He’s too powerful almost without ill effect (other than the cost that finally gets revealed for coming back from the dead; that was a well deserved punch to the gut).
