Heir.

"Heir" by Sabaa Tahir is a propulsive and action-packed duology that takes place 20 years after the events of the Ember in the Ashes series. The story follows two main characters, Aiz and Sirsha, as they navigate a world threatened by both human and supernatural forces. Aiz, an orphaned Kegari-born, escapes prison to find the all-powerful cleric who can save her people from a false prophet. Meanwhile, Sirsha, a banished Jaduna tracker, is contracted to hunt a killer targeting children. The book expertly balances a diverse cast of characters and builds on established lore, making it an engaging read for both longtime fans and newcomers. [Extracted from the article]
