Poisonous clouds spill from the sky and erase the sun. Buildings collapse. Communications fail. Corrosive fog consumes everything in its path.

Emily Stark flees her crumbling home with baby sister Sammi and shelters with a shellshocked band of survivors. As she tends the injured and risks her life gathering supplies, she is keeping a secret… her father, her hero, caused this disaster.

Fifteen years later. Against all odds, Sammi has grown up in the suffocating darkness and found love with soulmate Declan Chambers. When their hopes of a life together are jeopardised by mutiny in their commune, they slip past the guards and seek a life beyond its walls.

But burning fog isn’t the only danger to face them in the wilderness. A savage gang called The Outsiders attacks anyone who crosses their path, even snatching children from their parents’ arms.

Emily lost her young son to The Outsiders and she fears for her sister’s life beyond the commune. Not knowing where Sammi could be in the darkness, Emily has only one chance to save her: her father. Only she knows he has the power to return sunlight to earth, and only she knows where he is: deep inside the machine that churns the dark skies to acid.

Can Emily find her father and make him reverse the catastrophe he caused? And will Sammi and Declan’s love be enough to survive in the brutal fallen skies?
