In their fourth adventure together, Mystic and Sage take their half-brother to Cornwall, where the two mages vanish before his very eyes. Now, Cecil has no choice, but to believe their tall tales. The siblings are transported to an elven realm, where they meet Ashe's family for the first time. Lord Upton wants his anti-matter canister back, but there is no safe way to give it to him. Neither the elves, nor the fae have electricity, to recharge the battery of the canister, so how will they manage to overcome that obstacle safely? Zola takes a leave of absence and the mages sorely miss her psychic input. Along the way, the mages manage to acquire a new companion, are duped by a changeling, trick a unicorn and meet the evil fae king, Oberon. Why are they in the elven kingdom in the first place and their gracious hosts have ulterior motives, which are yet to be uncovered.
