Ward Holden considers himself the creator of a utopia. As a hapless college student, he found himself in nearly complete control over a revolution in physics. Advances in material science, unlimited energy, and an explosive shift in the meaning of wealth are all in the hands of a guy who doesn't quite know what he's doing.

The time is coming when everything people could want for themselves and their families is available with the push of a button. Cheap production, safe homes, and unlimited energy to power it all. But giving up a way of life is hard, even if that way of life causes poverty, starvation, and worse. But history moves on, and doesn't care about men or mice.

King in the Castle is the memoir of one man who managed to ride a wave of technological breakthroughs to success and power as humanity comes closer to a post-scarcity existence.
