Summary
Cassie Kent has been a superhero for two years—long enough to know a cape doesn’t make life simpler. Chicago is loud, chaotic, always on the brink, and she spends most days airborne putting out fires. She works alone, avoiding teams, politics, and especially the Guardians of the Globe. Their polished pitches can’t shake her instinct that something’s wrong. Trust gets people hurt.
Off-duty, she’s painfully normal. She lives with her cousin Clark, goes to school, keeps her head down. Sharp‑tongued and stubborn, she doesn’t try to impress anyone—least of all her annoying neighbor Mark Grayson, who insists they’re friends. She expects to forget him after graduation.
Then Mark reveals he has powers.
One confession cracks her walls. Suddenly he’s not just a weird kid—he’s dangerous, unpredictable, tied to something bigger. Cassie is pulled into uncovering the truth about his father, facing the possibility that one of the world’s greatest heroes is its biggest threat, and realizing she can’t stay on the sidelines anymore.
