The Resonance of Shadow - R. A. Collins

Gideon Brooks exists in a world of perpetual noise. Born with "Indigo Sight," he sees the living and the dead as a swirling kaleidoscope of energy and history. To the mundane world, he is a ghost of a boy-slow, distracted, and failing out of the public school system.

But when night falls, Gideon finds his true home at the Virentia Institute, a secret academy hidden from the eyes of the ordinary, where those with the Sight are trained to police the boundaries of reality. As Gideon's suppressed intellect finally awakens, he transforms from a struggling outcast into a formidable prodigy, drawing the ire of the Institute's established elite.

However, the true danger lies beyond the classroom. Years later, as Gideon enters the university stage, the Indigo community splits into warring factions. His former classmates, once his only kin, have begun to sell their gifts to the highest bidders, manipulating global markets and shadow governments.

With the very fabric of the spectral dimension fraying under the weight of their greed, Gideon must rise as a Guardian. Alongside Lyra, a woman with a mysterious immunity to the Indigo world, Gideon must wage a war of wills to prevent a cataclysm that would merge the world of the living with the chaos of the dead.
