Charlie's weeks have been filled with dwarves, kobolds, pixies, and humans, as he's sought to avenge his father's death and stop the dastardly Iron Cog from their plans to sow chaos throughout the world. Now his journey takes him to Marburg, Germany, where he and his friends must uncover the secrets of a hidden kobold library in order to save civilization--and their own skins. This dramatic conclusion to the trilogy will have readers cheering on its unlikely hero to the very last page!
