With the arrival of 11th grade, Hamilton Dinger has no shortage of activities to pursue. With his job at the mayor's office, schoolwork, and fighting off evil, he has no time to worry about Starry Knight's recent betrayal and his relentless fixation with her.

Pushing past his emotional turmoil, he works with Aleia and Elysian to uncover the truth about the Seven Deadly Sinisters and his supernatural origins. When disaster strikes once more, Hamilton and his friends realize the only way to prevent chaos from taking over Apollo City, and eventually the world, is to find the answers to the questions hidden deep inside his heart and mind.
