While I enjoyed this book, the author made a lot of bad choices that caused the story to depreciate in quality and sense as it went on.
So many plot holes, retcons, incoherence, confusion and unanswered questions. 

Zymon was one of worst parts, a one dimensional character with no wealth or power (yes he was prism-elect and prism for a time) who somehow has the Lightguards obeying his every command. I don't even have to list the reasons why all that was stupid and clearly a lazy implementation to keep the characters busy inside the Chromeria.

In the previous book it was revealed that Andross was Kip's real father, and was Dazen's youngest half-brother. Dazen admits many times over all the books that he doesn't feel much for Kip and he's just another tool in his arsenal, and yet, suddenly Dazen keeps referring to him as his son, Andross being the real father is never even spoke about at all, neither in dialogue or narration. Kip is never told, Dazen never reveals it. It seems like the author tried a cheap shock-factor trick in the previous book and regretted it and so decided to just not mention it and hope it's forgotten. No. 

Now we're told Gavin hunted immortals and imprisoned them in his Color Prison, which makes the first couple of books Gavin chapters with him trying to escape even more confusing and cheap. We're told Gavin was dead ever since Sundered Rock, so what was the point of these chapters from his perspective escaping the prisons when Dazen was far away from them. What? Was it the immortals themselves breaking the fourth wall to trick the reader or something? It was clearly initially shock-factor that Weeks abandoned later and created plot holes. 

So Kip was the Lightbringer, and Andross was so consumed by his own arrogance and pursuit to be unmatched in all things that he thought himself the centre of prophecy and somehow convinced his wife he was the Lightbringer and they sacrificed their youngest son, got their eldest to do it. Righhhhtt. Makes sense, most arrogant character thought himself the most important man in history. And Felia let him do all he did? For this? And bedding Katalina Deluria? And Kip giving away the Lightbringer mantle to him was ridiculous. And why was it necessary for Kip and Andross to play a few games of Nine Kings preparations for them at the brink of war?

This book, while enjoyable, felt so cheap. It felt improvised, I've noticed the past few books, ever since the black luxin memory loss was revealed, it was a cheap mechanic added to allow the author to change whatever he wanted to create as many twists for shock-value as he wanted and say it was memory loss, lazy. So many things foreshadowed and abandoned, things out I to play and flipped on its ass because he last minute thought something else sounded better yet didn't makes sense, such as Kip falling for Tisis and her being suddenly nice with a heart of gold???

There's so much more I could point out, but, despite the plethora of bad choices, I enjoyed it. I just needed to bring these issues up.
