The Warrior From Siata - Ken Bastian

This time Shaelene Willoughby is called upon to go back in time, rather than doing it by accident. The villages she'd come to think of as home in her former adventure are now under the rule of the cruel Aunu'u, and in need of rescue. Sina, her mentor as a warrior last time, teams up with her in a daring attempt to save the villages. But will it be enough to stop an even greater threat, or will she witness the end of days for her beloved people?
