Key trilogy

Single mother Zoe McCourt must struggle against man and magic when she becomes the last of her friends to follow the clues that will lead her to the key of valor which when combined with the keys of light and knowledge will free the Daughters of Glass, three Celtic demigoddesses imprisoned by an evil sorcerer.

Librarian Dana Steele, one of the three young women in a quest for the keys to a mystical box that holds the trapped souls of three Celtic demigoddesses imprisoned by a jealous sorcerer, is led to author Jack Hawke, but their prior romantic history complicates things when the two of them are forced into working together to locate the next key.

A mysterious invitation brings three very different young women to Warrior's Peak, a castlelike estate outside of Pleasant Valley, Pennsylvania, where their enigmatic hosts offer the opportunity to participate in an unusual quest. Each of the women will have 28 days to find one of the keys to a mystical box, which holds the trapped souls of three Celtic demigoddesses.
