Thrown into a prison built for monsters, she becomes the storm they never saw coming. Rei is human-avian and dangerous-but she's also just a girl. A girl snatched from her life and dropped into an all-boys high-security prison, where failed experiments and violent inmates claw for power, and guards treat pain like policy. They test the boys. They torment her. But Rei doesn't break. She fights back-with Muay Thai fists, tech-savvy tactics, and secrets even she's afraid to unleash. In the chaos, she finds Fang and Iggy-muted wings behind barred doors. Together, they plan their escape. And when freedom comes, it brings more questions than answers: Why doesn't Rei bleed? Why hasn't anyone seen her wings? And why does Iggy carry rage he won't speak aloud? As the trio runs from capture and dives into fractured loyalties, jealous ex-leaders, and hidden powers, Rei becomes the threat everyone underestimated. But power has its price-and healing comes with risk. Especially when the truth forces her to reveal what she's been hiding all along.

Ru Sanchez, 16, doesn't give much thought to her future. All she cares about is her little brother Remy, newly admitted to the most elite school in East London. Remy is her ticket out-the one who can rescue both of them from their broken council flat, from the silence where their mother should be. But when Remy is stabbed, and their emotionally absent mother takes her own life, Ru's world collapses. With nowhere to go and no one left to trust, Ru turns to drugs. She hangs out with the wrong crowds. Messes with the wrong things. Ru should be dead. But instead... she wakes up in rehab. Ayden Monroe, 17, doesn't need to worry about his future-it's already mapped out. Heir to a multimillion-pound legacy, expected to run his father's empire, Ayden's path is paved with privilege. Until his little sister Daisy dies. And Ayden breaks. The fame fades. The cameras vanish. The drugs come faster. Ayden should be dead. But instead... he wakes up in rehab. Their paths cross in the Pen Mates program, where patients are assigned to write each other letters. It's forced, awkward, and relentless-truth bleeding out in ink long before either of them is ready. But grief doesn't wait. Healing doesn't ask permission. And sometimes the person you never meant to speak to becomes the one who finally hears you.
