For twenty years, Dr. James Thabo has lived with a ghost on his tongue. A childhood trauma in his ancestral African village left him with a unique and visceral form of PTSD: he can literally taste the memory of ash. Now a respected therapist, he has built a fragile peace, a life of meticulous order designed by his brilliant architect brother, Emery—the one person who can hold the blueprint when James's world goes dark. But when a series of terrifying episodes threatens to consume him, James is forced to return to the place where his nightmare began, armed with his brother's unwavering loyalty and a desperate hope to exorcise the ghosts of his past.

What they uncover in Kwa'Mtimba is not a forgotten superstition, but a chillingly modern horror. They find themselves in the grip of a "theology of hunger"—a monstrous ideology that links the primal rituals of a jungle cult to the nihilistic appetite of the world's most powerful elite. The village is merely a franchise, a place where the life force of outsiders is harvested to feed an ancient hunger that now wears a corporate, global face. The brothers are no longer just survivors of a past trauma; they are the primary targets of a vast, invisible network that sees their souls as the ultimate prize.

Their hunt for answers leads them to a shadowy mastermind known only as The Curator, a benevolent public figure who secretly presides over a vast network of consumption. But The Curator is untouchable, protected by an ingenious digital failsafe that links his survival to the stability of the entire global order—a doomsday machine that would trigger worldwide chaos if he were ever captured or killed.

With the world hanging in the balance, the battlefield must shift from the physical to the psychological. James, a healer who mends broken minds, must become a weapon, tasked with deconstructing the myth of a god by haunting him with the ghosts of his own making. A harrowing journey from the heart of Africa to the corridors of global power, Fluorescent Heart is a breathtaking thriller that explores the nature of trauma, the chilling parallels between ancient faith and modern greed, and the unbreakable bonds that illuminate the path home. It is a testament to a brother's love—a quiet, resilient, and fluorescent heart that glows brightest when the world finally goes dark.
