Those who hunt monsters must be careful not to become monsters themselves.

In another life, before human traffickers murdered her husband and stole her children, Faith McMann was a wife, mother and teacher. Now she has become Furious, a merciless avenger on a deadly mission to retrieve her young son and daughter, no matter the cost.

Aided by unlikely but steadfast allies, the giant Beast and fragile Rage, Faith plunges ever deeper into a sickening underworld of sexual exploitation and slavery with steel-forged determination and righteous anger.

In this powerful, suspenseful conclusion to the Faith McMann trilogy, Faith is haunted by questions: Even if her children are recovered, will they be broken beyond repair? What terrible sacrifices will their rescue require? What are the limits of loyalty and love in a world that preys on innocents? And after her brutal awakening to the darkest aspects of human nature, what will remain of her own self?
