The Fire Opal — Regina McBride

There was a time when Maeve O'Tullagh led a simple life; a time when she and her mother, Nuala, collected kelp on the foreshore near their cottage in Ard Macha; a time when she played among the Celtic ruins with her older brothers and daydreamed about the legendary Holy Isles, an enchanted land ruled in a past age by a beautiful goddess.

But after Maeve's sister, Ishleen, is born, her mother sinks into a deep, impenetrable trance. For years, Maeve tries to help her mother awaken, and then the unthinkable happens: Ishleen succumbs to the same mysterious ailment as Nuala.

Heartbroken to think that her sister and her mother might be lost to her forever, Maeve sets off on an unimaginable quest to a world filled with fantastical creatures, a web of secrets, a handsome, devious villain who will stop at nothing to have her hand in marriage--braving them all to retrieve a powerful glowing stone that will help her recover the souls of her loved ones and bring them home to Ard Macha.
