Reading "I Die in a Good Cause," originally published in 1970, is to connect with the great national narrative that once electrified Ashe himself. Author O Luing was born only a few months before Ashe's death in 1917, and his book reminds us of the enduring power of a legacy.

Thomas Ashe was only 32 when he died (after a so-called “botched” force-feeding while on hunger strike in Mountjoy prison). Ashe and his fellow revolutionary inmates had insisted they be categorized as political prisoners, and their hunger strikes had commenced in the hope of conceding the point.

But as so often in the story of the struggle for Irish independence, much of Ashe's legacy now comes to us from the lingering questions over who he would have been, what part he might have played in the wider national story, had his promise not been so cruelly cut short.

There is more than a hint of reverence in this clear-eyed but celebratory telling. As long as there is an Ireland it's a story that will not age and a book that will never be out of print.
