The Renegades face their greatest challenge yet - extreme sea level rises and a sinister new plot from their arch-enemy.
Mo, Leon, and Katelyn are on the move again, along with Amazon activist Alma. They've been tracking the movements of their long-time nemesis - businessman-turned-supervillain Jason Greenleaf - and he has a new plot up his sleeve.
But as they race to uncover the meaning behind Jason's new friends The League and the mysterious new serum he is developing, the team must reckon with multiple challenges. Sea levels are rising and strange creatures in the mangrove forests of Bangladesh are at risk of dying out. With so many threats to the Earth mounting, could this all be too much, even for the Renegades?
