Bill Gates is one of the most powerful figures of the past four decades. But the world-famous public image he has so carefully crafted is not the whole truth. In this explosive new book, Anupreeta Das (finance editor of theNew York Times) takes you behind the facade.

From his early years, when he was a divisive figure in the burgeoning tech industry, we see the Microsoft co-founder morph into a ruthless capitalist, only to change yet again when he fashions himself into a global do-gooder.

But as Das's revelatory reporting shows us: billionaires have secrets and philanthropy can have a dark side.

Drawing upon hundreds of interviews with current and former employees of the Gates Foundation, Microsoft, and those with insight into the Gates universe, Das delves into Gates's relationships with Warren Buffett, Jeffrey Epstein, Melinda French Gates and others to uncover the man behind the persona. In telling Gates's story, Das also provides a new way to think about how billionaires wield their influence, manipulate their image and pursue philanthropy to achieve their own ends.

Billionaire, Nerd, Saviour, Kingis a gripping story of wealth, power and reputation; it will open your eyes to the ways in which the world's richest people hold us in their thrall.
