Chalice, the sacred supreme unicorn, has been captured with other unicorns by the Weers—wolf-like monsters whose evil leader, Rashark, is stealing all of their magic. And because Chalice has the most powerful of magic of all the unicorns, Rashark wants him the most. For the moment, Chalice’s disguise is keeping him from Rashark’s notice—but it won’t hide him for long. In the meantime, a mysterious old man appears at an orphanage in Ireland. He tells a small boy named Eoin that he is the only one in all the lands with the power to rescue Chalice. When he reveals Eoin’s secret powers, the boy reluctantly agrees to help. But will Eoin’s magic be enough to rescue Chalice from Rashark’s lair before it’s too late?
