Finn McCool was born a giant with the gift of Celtic wit but--at least in his youth--is prone to bad luck. One day McCool will become the chieftain of Fianna hunter-warriors, and the greatest Irish folk hero of all time. But until then, he has some growing up to do.   In The Green Hero, renowned mythologist Bernard Evslin recounts the tales of Finn McCool's early years: his attempts to woo Murtha, the girl he fell in love with when he was just three days old; his torment by the Fish-hag; his struggles with the whims of the goddess Amara; and more. This amusing collection retells the early exploits of a man who became a legend.
