Thor is finally released from his pain. Nothing in life and death is easy.
The symbol of a circle is very important in this book. The seasons circle, the story circles back to the first book, Johns life with his shellan circles, No One's life circles and finally Lassiter's life circles. If you look more deeply you will notice many more important circles also. A very well thought out story, with all of the angst, love and passion of previous books. As is typical it is very difficult to compare one to the other. The similarities are really not that important. Each book is as different as the characters they are about.
Both Thor's character and No One's character as so well developed it is easy to understand their thoughts and feelings. It is easy to have a visual picture in mind as the story develops. In this book all of the characters, including some shellans are refered to. It is always nice to drop by and say hi to old friends.
