Book 5 of the Tower series. We see Thorn become yet even more powerful. A new powerful foe now opposes Thorn and I like that he is still strong enough to create a struggle. I loved the progress and changes, but do wish that this book had been almost double as there were a lot of other items that the author could have done into. That said that speaks to how well written this novel is. If you cannot image ties as a video game, then you need to read it again. Jump into this series and enjoy.
