Amelia fled to the Sanctuary, desperate for the cure to the Hydra virus. She finds safety in the walled enclave, and the promise of a luxurious life she thought she'd lost forever. She can have it all -- if she's willing to betray the people she loves. Offered the vengeance he's always longed for, Gabriel faces his own terrible crucible. He can attack the Sanctuary, bring down the elites, and save the cure -- but doing so will turn him into the man he swore he'd never become again ... On the brink of war, the survivors must choose -- escape with their lives, or stay and fight for the hope of something better, risking everything that matters in the process.
