Across America, technology has been eclipsed by magic, as ordinary people become the embodiments of their darkest desires, deepest fears — and purest selves. Searching for the source of this terrifying phenomenon — and to save his sister Tina, transformed by it into one of the ethereal creatures known as flares — former lawyer Cal Griffin and his band of unlikely heroes follow the visions of the charming lunatic Goldie and the fragile song of a cursed bluesman to a secret haven hidden from its malevolent power. The domain of the bluesman and his protector Magritte — a callgirl turned flare — is a wondrous sanctuary from the madness. But how long can it survive if the evil beyond it is allowed to flourish? For the world is unraveling little by little. And the salvation of everything left worth saving requires that Cal and his companions journey deep into the very heart and soul of darkness to confront the beast ruling the Ruby City once called Chicago. But first they must conquer the darkness within themselves.
