History loves to celebrate brilliance. This book lingers on what happens after brilliance stops obeying the rules.

Gone Mad is a guided descent into the lives of extraordinary minds who crossed the thin line between vision and fixation, genius and delusion. These are inventors who trusted their ideas more than gravity, artists who mistook suffering for truth, leaders who believed destiny had chosen them alone, and prophets who turned conviction into catastrophe.

From backyard nuclear reactors and homemade parachutes to cults, conspiracies, self-made empires, and spectacular collapses, this book chronicles what happens when intelligence loses its brakes. Each chapter captures a single figure at the moment their brilliance curdled, when confidence hardened into obsession and the world could no longer follow.

This is not a catalog of illness or cruelty. It is a study of unchecked belief. The kind that builds masterpieces, ignites movements, and occasionally burns everything down with it.

Darkly fascinating, sharply written, and unapologetically human, Gone Mad asks an uncomfortable question that echoes through every era:

How far can genius go…
before it goes too far?

For readers drawn to brilliant failures, dangerous ideas, and the irresistible pull of the abyss.
