Defiant YA Dystopian Series Omnibus. Defiant, #5

The rules are killing them. The truth might save them. In a shattered world ruled by fear and silence, twins Alex and Caleb were never meant to lead a revolution. But when a deadly epidemic sweeps through their broken society-and the ones in charge do nothing to stop it-their choice becomes terrifyingly simple: obey the rules and die, or break them and fight to survive. What begins as a desperate search for answers becomes a dangerous journey through lies, secrets, and the ruins of a world that forgot how to care.
With each step, the twins unravel a truth more explosive than they ever imagined-and discover that even hope can be weaponized. Betrayal. Sacrifice. Rebellion. If you devoured The Hunger Games and Divergent, get ready to lose yourself in this emotionally charged, adrenaline-fueled four-book series about two siblings who risk everything to challenge a system built on control. Their world is falling apart.
Will they save it-or burn it down?
