In late 2024 Ireland, a nation of just 7 million people, stood at the top of rugby union's world rankings.

Ireland's rise to such an exalted position has been the great triumph of rugby's professional era. For a nation that fought tooth and nail to keep the game amateur, their progress since 2000 has been extraordinary. The trophies, once so rare in Irish rugby hands, have become almost commonplace. Grand Slams, Six Nations Championships, Triple Crowns have all stood in the IRFU offices in Dublin.

But that is the top tier of the game. What is the health of the sport at other levels all around Ireland? In this book award-winning international rugby writer Peter Bills seeks to take the pulse of the game at every level - schools, clubs, provinces - as well as the fast-expanding women's game. For if rugby at grassroots level withers, the decline will affect everyone. And how can rugby learn to live side by side with the ubiquitous GAA?

Featuring interviews with some legendary names of Irish rugby, such as Keith Wood, Willie John McBride, Tony Ward, Bill Mulcahy, Gordon D'Arcy, Trevor Ringland, Nigel Carr and Tommy Bowe, we also hear from men and women from junior and club rugby, at clubs like Dingle, Kinsale, Monkstown, Boyne, Westport, City of Derry, Donegal Town, Omagh and Oughterard. All of them are doing stirring work behind the scenes for their local clubs and communities as Bills goes in search of the soul of Irish rugby.
