With more keys making themselves known, and the depths of the Locke family's mystery ever-expanding, Dodge's desperation to end his shadowy quest drives the inhabitants of Keyhouse ever closer to a revealing conclusion.

The Locke children have grown accustomed to the myriad magical keys discovered within their ancestral family home of Keyhouse. They have also grown accustomed to tragedy. What they may not be prepared for is just how closely danger stalks their every move as Lucas "Dodge" Caravaggio, alias Zack Wells, continues his relentless quest for the key to the black door.

New keys and old specters join the story as innocence is lost and determination is forged in this collection of Joe Hill and Gabriel Rodriguez's Locke & Key: Keys to the Kingdom.
