3.5 stars. I'm still really enjoying this series. I'm probably in the minority in that this was not my favorite book so far. I never took a huge liking to Carl though he did grow on me a bit more in this story. He tries so hard to help everyone but never seems to make the right decisions.
One of the things I do enjoy is seeing the other characters, especially Titus and Andreas. I'm looking forward to the next installment to see where things go from here.
