Maeve, Ireland's greatest heroine of antiquity, is still learning the ropes. The Irish warrior, here still daughter of the king of Connacht, finds herself in the frontier of enemy territory with a small troop, and, worse than that, they discover that a Slaugh party, a swarm of evil fairies from the dark side of the spiritual world are in their way, and heading to their homes. Will Maeve and her father´s troop be able to hold off these forces or will this be the end of the Connaught kingdom, and Maeve's world?
