I think this books deserves about 3.75 stars, but decided to round it up since I thought the action picked up a bit toward the end. The beginning was a bit slow and there were actually several days where I just didn't want to read any more since things were dragging along at a snail's pace. I finally picked it up late last night and ended up staying awake way longer than I intended.
My main issue with this book was there were several moments where things seemed overly fake and forced. "Angelfall" was the same way. I actually found Pen a bit annoying at times and was thoroughly glad when Raffe rescued her from the grisly angel party at the new aerie. I was exceedingly happy to see them back together! The banter between Raffe and Pen is pretty awesome :).
I guess what I'm getting at is conflicts and seemingly insurmountable obstacles had a way of resolving themselves in an unbelievable manner. The whole "Pooky Bear" bit was also a touch too saccharine for my liking as well. The ending was pretty phenomenal though, which was the same for "Angelfall."
