Lost powers. Broken trust. Once last chance to make it right.

When a long-dead enemy comes back from the dead, Rupert Darney must reunite the Guardians, a once-legendary team fractured by time, but old rivalries may tear them apart before the battle even begins. Elsewhere, Oliver Mitchell journeys to a secret metahuman town, desperate to uncover the truth and regain what has been lost. And Sasha Yates, reeling from family tragedy and a move across the ocean, discovers her father’s dark ties to the Guardians’ greatest foe.

Meanwhile, their paths are pulled together when an even greater threat arises from the darkness.

Can the Guardians come together once more? Can Oliver reclaim what was his? And will Sasha rise to become the hero the world never saw coming?
