Soul Eater is the third book in the Chronicles of Ancient Darkness series written by Michelle Paver and illustrated by Geoff Taylor.

Soul Eater is preceded by Wolf Brother (2004) and Spirit Walker (2005), and followed by Outcast (2007), Oath Breaker (2008), Ghost Hunter (2009), Viper's Daughter (2020), Skin Taker (2021), and Wolfbane (2022).

During their journey, Torak spirit walks[note 1] in a raven, and discovers that the Soul Eaters, a group of evil mages, have captured Wolf.

To maintain his disguise, Torak helps the Soul Eaters in their quest to release an army of demons, while Renn also enters their cave.

[2] School Library Journal's Walter Minkel discussed how "Paver describes how much labor and constant attention go into simply surviving in a world so hostile to humanity, and readers will be kept on the edge of their chairs as they follow the struggle of characters who risk their lives every day trying to accomplish a task that seems certain to lead to their death".
