I haven't time to write a full review so I am going to keep this brief. If you haven't started this series yet, you NEED TO. 
 For five books now we have followed the journey of Hadrian and Royce. I must say, for the amount of books involved, Sullivan has kept this story very tight. With my love for big epics from authors like Erikson, Hamilton and Reynolds, whose side stories become novels in themselves, it is really great to read a story with a central story with almost no side stories. Everything correlates to the main story and if there is a branch it is quickly brought back to relevance to the plot. 
 The characters just continue to grow and for a character dev fan like me, that makes all the difference between that 4 or 4.5 star to the big one. This book has finally tipped me into the 5 star range. This one had it all. I was absolutely engrossed and actually sat in my car being late for work the other day because the build up and anticipation for a jousting event had me on the edge of my seat. I haven't felt that much anticipation since the Gunslinger took on Blaine in a riddles contest. 
 This author has grown and grown with this series and has easily become one of my favourite. A wonderful series that I am completely hooked on.
