Dark Magic, Hidden Destiny For three centuries a divine prophecy and a line of warrior queens protected Skala. But the people grew complacent and Erius, a usurper king, claimed his young half sister’s throne. Now plague and drought stalk the land, war with Skala’s ancient rival Plenimar drains the country’s lifeblood, and to be born female into the royal line has become a death sentence as the king fights to ensure the succession of his only heir, a son. For King Erius the greatest threat comes from his own line — and from Illior’s faithful, who spread the Oracle’s words to a doubting populace. As noblewomen young and old perish mysteriously, the king’s nephew — his sister’s only child — grows toward manhood. But unbeknownst to the king or the boy, strange, haunted Tobin is the princess’s daughter, given male form by a dark magic to protect her until she can claim her rightful destiny. Only Tobin’s noble father, two wizards of Illior, and an outlawed forest witch know the truth. Only they can protect young Tobin from a king’s wrath, a mother’s madness, and the terrifying rage of her brother’s demon spirit, determined to avenge his brutal murder.... less

He is to rule--not as he is but as he was born: a woman... moreA trick of magic, a twist of fate.As the orphaned nephew of the king, trusted companion to his cousin, and second heir to the throne of Skala, Prince Tobin’s future is clear. But not as clear as the spring in which a hill witch shows him his true face--and his secret destiny....Now Tobin carries a burden he cannot share with even his closest friend, Ki, his squire. He is to rule--not as he is but as he was born: a woman. Given the shape of a boy by dark magic, Tobin is the last hope of the people of Illior--those who desperately seek a return to the old ways, when Skala was ruled by a line of warrior queens. They still believe that only a woman can lift the war, famine, and pestilence that have run rampant through the land since the king usurped his half sister’s throne. It is these outlaw wizards and witches who protect Tobin--and it is for them that Tobin must accept his fate.With the unsuspecting yet fiercely loyal Ki at his side, Tobin must turn traitor against the only blood ties he has left. He must lift the masks of Skala’s rulers to show their true colors--before he can reveal the power of the woman within himself. less
