Out of the swirling mists of time and magic, three figures step into the battle camp of the warrior-queen Maeve. One is a Druid, a dark-spirited wizard seeking the source of his power.
The other two are Rosemary and Jimmy, modern-day Canadian teenagers on a summer visit to Ireland. Drawn by enchantment without their knowledge or consent, they have arrived in the fierce world of the ancient Celts.
Battles erupt, treachery abounds, and death threatens them on every side. Then the Druid disappears, taking with him all hope of a return to their world.
