She defeated a demon and imprisoned a mad druid in a crystal serpent's egg. She changed the course of history, and never doubted which side she was on. Now the rules have changed. In the shifting landscapes Celts call the otherworld, friends may be foes, good deeds yield evil results, and childhood fantasies become adult nightmares.

Braving pillaging Vikings on the Loire, battling a crazy sorcerer in the Broceliande forest, and confronting the nine Gallicenae, druidesses who rule the Isle of the Dead, the only friend Pierrette can trust may be the Evil one himself, the Eater of Gods.

And now the last battle looms, a battle in which Pierrette, she who would save the Past and the Future, can trust no one and nothing, not even the devil she thought she knew.

[The Sacred Pool, first of Pierrette's adventures is] "Immensely readable and elegantly simple in execution . . . this vivid reimagining of Western humanity's turbid adolescence engages, enchants and enthralls."
