Wildfire — Jo Clayton

MAGIC'S CAPTIVE
Return to the universe of Wild Magic, where rival gods, mischievous elementals, powerful sorcerers, clairvoyant sibyls and magical beings of all description play intricate games of power and wizardry.

Forever separated from the only home and family she has ever known, young Faan embarks upon a difficult and daring search to find her true mother--a powerful sorceress who lies bespelled in a magical sleep, far away on the isle of Faan's birth. But distance and old sorceries are not all which separate Faan and her mother, for a sibyl has decreed that her fate is inextricably entwined with the fates of two others, both pawns in the power struggles between gods and power-hungry magicians. And Faan, not yet fully trained in the use of her own ever-growing magical talents, finds herself once again embroiled in the deadly sorcerous battles of those who seek to control her world.
