In 2001, Cormac McAnallen was voted Young Footballer of the Year. In 2003, he helped Tyrone to its first-ever All-Ireland championship win, and was named an All-Star. He was, by any measure, one of the best and most promising young footballers in Ireland.

But in March 2004, Cormac McAnallen died suddenly of an undetected heart condition. He was, truly, a young star cut down just as he entered his prime. As he worked his way up through the ranks of club, school and inter-county football, Cormac almost always had his brother Donal - just a year older - by his side. Nobody else in the world knew as well as Donal did how badly Cormac wanted to succeed, how hard he worked, or how much thought he put into his game.

In The Pursuit of Perfection, Donal McAnallen draws upon Cormac's diaries and frank self-assessments, and his own memories of their experiences, to create a remarkable portrait of a young sportsman's mindset and methods. It is both one of the most remarkable GAA books ever written and - in its intimacy and depth - a book that transcends Gaelic games.

'Exceptional ... Unique and compelling, raw and moving ... Much better than any myth or legend' Paul Rouse, Irish Examiner

'A touching, sometimes bracing biography ... It feels like a final word, the family's last say on how he lived and how he died and how he ought to be remembered.' Malachy Clerkin, Irish Times

'Beautifully told' Dermot Crowe, Sunday Independent

'Stirs something deep around the concept of brotherhood' Belfast Telegraph

'Heart-rending ... It is a painstakingly researched work - aided by the fact that both brothers kept meticulous diaries - and what's striking about the story is the pressure that Cormac was under despite or maybe because of his success with Tyrone' Sunday World
