''Invaluable . . . A whistle-stop tour down through the ages'' Jarlath Burns, GAA President

The ultimate book to celebrate 140 years of Ireland's greatest sporting and cultural institution - The GAA.

Pulse of the Nation is a celebration of the GAA's 140 years at the centre of Irish life, from its foundation in November 1884 to the present-day institution that has expanded massively at home and abroad.

It zones in on the greatest players in football and hurling, ranking them one-to-ten, accompanied by profiles, in each of the fifteen positions in both codes.

The greatest day for all 32 counties is explored, along with a trawl through the various competitions, from the All-Ireland championships with their ''Heartbeat of the Irish Summer'' billing, to those that were once popular but are no longer in place.

Controversies are examined, the changed managerial environment is assessed - including the impact of some of the biggest names from Kevin Heffernan to Mick O'Dwyer, from Brian Cody to John Kiely - and the covers are lifted on the GAA's role in Ireland's social and cultural history, including the growth in popularity of camogie and ladies' football. Written by award-winning sports journalists Martin Breheny and Donal Keenan, this is the ultimate publication for the GAA's 140th anniversary.
