Winner of three All-Ireland senior hurling medals and six All-Star awards, Maher was one of Tipperary's key men for over a decade while with his club, Thurles Sarsfields, he ignited a revival that led to seven county titles. Born into a passionate GAA family, hurling was Maher's life.

Until, in spring 2022, he was forced into a shock early retirement. Here, he looks at the events leading up to the injury that ended his career and takes us back through his life with hurling to give an honest and down-to-earth account of the sport, the club and the county that means so much to him. From being a central figure in the great Tipperary-Kilkenny rivalry, to the unforgettable trilogy of Tipperary-Galway All-Ireland semi-finals, to his side of one of hurling's most famous tackles, All on the Line gives an unforgettable insight into the commitment it takes to be a GAA player in modern Ireland, and the passion this great hurler holds for his club and county.
