With their alien teammates, Nita, Kit, and Dairine must race to search worlds known and unknown for the secret weapon the Powers That Be have promised them--before the minions of the sinister Lone Power find it first. And then, for the first time in millenia, the wizards must go to war. . . .

Young wizards Nita and Kit face their most terrifying challenge yet: Nita's bratty little sister, Dairine. Not only is Dairine far too smart for a ten-year-old, she also has recently become a wizard, and worse yet, a wizard with almost limitless power. When Dairine's computerized wizard's manual glibly sends her off on her novice adventure - her Ordeal - Kit and Nita end up chasing her across the galaxy, trying to catch up with Dairine before she gets into trouble so deep that not even her brains can rescue her.

To give Nita a vacation from magic, Nita's parents pack her off for a month-long stay with her eccentric aunt in Ireland. But Ireland is even thicker with magical doings than the United States, and Nita soon finds herself and a host of Irish wizards battling creatures from a nightmare Ireland, one in which humankind is the stuff of tales and storybooks and where the legends and monsters of the country's mythology are a deadly reality.
