|video=|summary=A very epic - both in action and length - fantasy that takes readers deeper into the brilliant world that Weeks created in [[Lightbringer: The Black Prismby Brent Weeks|The Black Prism]]. Great action, great characters and lots of politics and manipulations to keep the reader on their toes to the very last pages. Superb reading.|cover=1841499072|aznuk=1841499072|aznus=1841499072

Gavin Guile thought he had five years left to complete his seven great purposes. But now it seems he has less than one. He might be the Prism - the most powerful light drafter in the Seven Satrapies, capable of drafting huge amounts of light without risk of losing his mind to the colours - but he's lost blue. He can't see it or draft it.
