The city of Brighton is in chaos. Infernal science inverted half the population. The other half fights for survival. The Alchemancer series continues. Half of Brighton's population paid the price when Aaron failed to stop the Nullification Engine. The situation worsens when eslar invaders, led by Ensel Rhe's brother-in-law, Balrabbek, arrive in Brighton intent on completing Ingrid Kane's work. Forced into an alliance with them, Aaron soon realizes the engine's effect went well beyond the city's borders and that much more is at stake than he ever imagined. When Ensel Rhe learns of Balrabbek's arrival, he wants nothing more than to take revenge on him for the murder of his son. But his brother-in-law's deceit and his ambitions went much further than he thought. Now, he must end those ambitions, no matter the cost. Meanwhile, Serena flees from the chaos consuming Brighton, only to find that escape is a fleeting thing as her inability to control her magic continues to haunt her. When she learns of the Griffin's mission to retrieve the secrets of a lifesaving vitality serum, she sees it as a way to save both her people and herself.
