Summary:

Five extraordinary people with seemingly nothing in common share the bond of surviving a cataclysmic event. In a world devoid of super-heroes, they come together and discover that everything they know has been a lie, that the world we live in is not the one we believe it to be. To survive, they must unite and face the true masters of our universe. It's a world where literally anything can happen, and probably will!
