Book 9 of the Tower series. I love the Thorne books. This takes place in the demon realm. OT favorite titan is back kicking butts and finding new ways to advance. The only disappointing part is that he spent little time forging and really creating anything new and cool. Also, would love to see a new bump in the AI as now he is beginning to surpass its abilities in certain areas. Overall this is a strong series and looking forward to the next book.
