Ever since he rose up against his father and saved New Anglia from destruction, Ash has been struggling to adapt to his new life. He has nightmares every night, haunted by strange black orbs and his screaming dead mother. Ash is sure she's trying to warn him that the world is still in danger, and becomes determined to find a way to speak to her again - but communicating with the dead isn't easy, even for an alchemist as powerful as Ash.
It doesn't help that violent anti-alchemist sentiment is spreading across New Anglia. When Ash is captured by a radical alchemist group, inspired by his father's legacy, he must decide if alchemist rights can be trusted in the hands of the Houses, along with his partners Callum and Ramsay - or if Ash must follow the path his father laid for him, and become the leader of an alchemist revolution.
