The Legend of Finn is the life tale of Finn Mac Cumhal, the greatest mythic hero of ancient Ireland. Finn's father, Cumhal of Clan Baiscne, is assassinated on the night of his birth.

Cumhal was Lord Captain of the famed Fianna of Erin, a mounted knighthood of woodsmen warriors who risked their lives to protect their island country's many miles of rugged coastline from marauders and invaders. The Captaincy of the Fianna is a blood-right heritage passed from father to son and a position of enormous power in Erin, second only to the High King himself.

Young Finn grows up continually hunted by his father's enemies, who seek his death to steal that heritage. He must find a way to overcome enormous trials, of both mortal and immortal origin if ever he hopes to regain his father's ancestral seat.

Will Finn unlock the mysterious secret of the famed Salmon of Knowledge and defeat the hundred-year-deceased spirit of a legendary sage of history who challenges him to a magical game of chess? Will he be able to solve the riddle of the Hag at the Well of Healing Waters? Most frightening, how will Finn overcome Aillean of the Flaming Breath, a creature spawned in the dark of the underworld that visits great evil upon the Land of Erin, claiming the lives of any who confront it?Should Finn regain his ancestral heritage and come into the power of rule, what kind of leader will he become? How will he inspire, and what values will he teach? What merits his honored place in the ranks of other great pantheons of legend, whose life tales we have recounted for thousands of years to follow?Finn's tale is full of the whimsy of Faery, the guiding influences of the gods, and explores the most profound questions of honor, courage, heroism, and living by the precepts of a noble code. .
