Description
Hunted all their lives, they've had to fight the life-threatening and belief-defying battles pitting their strangth against the fearsome force of their shadowy enemies. But as their predators evolved, their unique ablilty to fly is no longer enough to save them. With their genes mutating to astonishing effect, the flock astablishes a new set of skills to unleash as they strive for survival. But just as they struggle to get to grips with these physical changes, emotionally they face new challenges too: life on the fringe of society can be a lonely existence.
Driven to the wastelands of Antarctica, each day brings a new threat for the flock. Danger is never far away and while fighting to save their own skin, they have a new mission to undertake - one with devastating global consequences.
