Interregnum: Inside the Grueling and Glamorous Battle to Become the Next King of Chess

A riveting chronicle of the battle for chess supremacy and the brilliant, eccentric, extremely online grandmasters changing an ancient game.

Every elite chess player dreams of becoming world champion, of wearing the wreath and going down in history. Yet for many of today's top grandmasters, that dream long seemed out of reach: Norwegian juggernaut Magnus Carlsen was just too good. So when Carlsen announced he wouldn't defend his world title for a fifth time, the rest of the best saw a chance finally to sit on the throne.

Interregnum follows these brilliant and often eccentric minds around the world as they vie to become world chess champion. It's a story of millennial greats whose time is running out. Of teenaged prodigies who refuse to wait their turn. Of triumph and heartbreak, aspiration and anxiety. Of an ancient sport experiencing a remarkable resurgence and of the extremely online enfants terribles changing the game.

Part sports chronicle, part paean, part character study, Interregnum offers something for both the chess-obsessed and the chess-curious as well as anyone who enjoys a riveting tale of struggle in sport or triumph of the intellect.
