Call of Madness (A Caithan Crusade Book 1)

In a land where magic is outlawed, a princess with magic talents is caught between loyalty and leading the rebellion in this fantasy series-starter. Magic has been forbidden in Caithe for 200 years. Those born with magic—the Lorngeld—are considered the devil's children. They are ruthlessly executed by the Caithan Church before they can be corrupted by mind-plague—the volatile madness that afflicts untrained wizards. Only King Kelwyn, artificially gifted with borrowed magic, is exempt from punishment. His daughter may not be so lucky. Impertinent and rebellious, Princess Athaya prefers to spend her time gambling and drinking rather than courting would-be suitors. Discovering that she is a natural-born wizard is an unwelcome surprise. But there are those who believe it is a gift, and that someone with Athaya's unique ability may be capable of leading the Lorngeld out of persecution. Torn between loyalty to her kingdom, her duty to the Lorngeld, and her own impulsive heart, Athaya must harness her burgeoning magic before it drives her mad, and learn to wield its power before those who fear it—and those who envy it—can destroy her.
