No Irish rugby player has ever achieved more, or been a source of more inspiration to teammates and fans alike, than Johnny Sexton.

The Sexton era - marked by four European Cups, four Six Nations championships (including two Grand Slams), a series win in New Zealand, two stints for Ireland at number 1 in the world, and the World Player of the Year award - was above all the time when Leinster and Ireland went from being underachievers to being overachievers.

In his hotly anticipated autobiography, Johnny tells the story of his life and explores the sources of his unmatched will to win. Always outspoken on and off the field, Sexton offers an honest look at his childhood, his seemingly inauspicious early experiences in club and professional rugby, his relationships with key teammates and coaches (including Brian O'Driscoll, Paul O'Connell, Ronan O'Gara, Joe Schmidt and Andy Farrell), and his ideas about the game.

Obsessed is more than just a brilliantly detailed account of a legendary playing career. It is also a work of deep self-exploration, tracing the psychological arc of a player who almost always felt embattled, who struggled with self-doubt, and who was still learning new lessons about being a team-mate and a leader into his late thirties. Intense, witty, perceptive and frank, Obsessed is an autobiography worthy of its author and the essential chronicle of an extraordinary era in Irish rugby.
