London, 2012: It arrives and with that the world is changed into an unending graveyard littered with the bones, wreckage, and memories of a dead past, gone forever.
London, 2032: Twenty years later, out of the ashes, a new world begins to rise, a place ruled by both loyalty and fear, and where the quest to be the first to regain lost knowledge is an ongoing battle for power. This is a place where laws are made and enforced by roving gangs – the Bloomsbury Boys, the Gardners, the Red Lady's Gang – who rule the streets and will do anything to protect their own.
The Four: Zane, Titus, Erin, and Eve. Living in this new world, they discover that they have abilities never before seen. And little do they know that as they search post-apocalyptic London for Titus' kidnapped sister that they will uncover the secret of It, and bring about a reckoning with the forces that almost destroyed all of humanity.
