Dana Swift closes the Wickery duology with Bound by Firelight, picking up directly after the cliffhanger of Cast in Firelight. Adraa wakes up in a brutal magical prison with her memory mostly intact and her ability to do magic compromised. The point of view alternates between her trying to survive inside and Jatin trying to find her from the outside.
The stakes are higher than in book one. Swift uses the prison setting to push Adraa into her hardest version of herself, and the political conspiracy that started in the previous book reaches its peak.
The romance from book one continues but takes a backseat to the larger stakes.
This can only be read after the first book. New readers should start with Cast in Firelight. For readers who liked the first, the conclusion does the work that duology second books are supposed to do, with most of the major threads landing.
