When Saotse rode across the treacherous ocean on an orca at the bidding of Oarsa, Power of the Sea, the blind maiden believed she had been chosen for a great destiny. But she hasn't heard Oarsa's voice in decades. Aged now, she has found her place among a peaceful, long lived people, though her adoptive sister, Uya, still blossoms with youth. Then, pregnant Uya is kidnapped, and the rest of her family is slaughtered when an army of mounted warriors strikes the defenseless capital, leaving Saotse grief stricken and alone. After Saotse finds refuge with strangers in a distant village, a new Power makes contact. Saotse embraces the opportunity to bury her bloodthirsty enemies in vengeance, but wielding the Power's bitter magic could cost her everything she is.
