I love the Ghostwalker's Series! When I read the book with Saber I had hoped there would be a book with Thorn. Truthfully, I can't remember who Sam is in the previous books. Thorn is absolutely awesome. I also loved all the the Japanese culture and Samurai that were in the book. Each book in this series is different and I love seeing how the "teams" evolve. There were only updates on teams one and two in this book which isn't surprising since the last several books were team three. Overall I loved the book. I stayed up all night the first night because I was just too into the book to stop reading!
