But life in this other world is about to change. Tragedy strikes when Jacob's younger brother, Will, follows him through the portal. Brutally attacked, Will is infected with a curse that is quickly transforming him into a Goyl--a ruthless killing machine, with skin made of stone.

Jacob is prepared to fight to save his brother, but in a land built on trickery and lies, Jacob will need all the wit, courage, and reckless spirit he can summon to reverse the dark spell--before it's too late.
