The snowmelt river

On the summit of the fabled mountain Slievenamon in Ireland there is a doorway to an ancient land of terrible power. The gate of Feimhin has lain closed for centuries, the secret of its opening long lost. But now four orphans drawn together by Fate must pass through the portal to face their destinies. What they find beyond is the enchanted but war-ravaged world of Tir, a strange land peopled by beings of magic. Here death waits at every corner and they must learn to fight if they are to survive. And they'd better learn quickly, because their enemy, the Tyrant of the Wastelands, whose fearsome Death Legion stalks the land, is growing in power.
