The full story of how Federer, Nadal and Djokovic dominated tennis's golden era - and changed the sport forever.

In Three Kings, award-winning author Mark Hodgkinson delivers the first definitive account of the most intense rivalry in sporting history - an era shaped not just by talent, but by three radically different minds.

Drawing on revealing interviews with coaches, former players, and those closest to the trio, Hodgkinson explores what made Federer so effortless yet ruthless, how Nadal turned pain into power, and why Djokovic created men's tennis's golden era.

From playing styles and psychological warfare to training, tension and turning points, this is a deep dive into the forces - personal, mental and physical - that pushed each man to the edge. Hodgkinson revisits the era's defining matches, capturing what it felt like to face a Federer pass, a Nadal forehand, or a Djokovic return - and asks the question the sport struggles to answer: who was the greatest of all time?
