Sword of Waters — Hilari Bell

The story begun in Shield of Stars continues here from Weasel's friend Arisa's point of view. Arisa's mother, formerly known as the dangerous bandit the Falcon, now holds a position of power. Therefore she encourages Arisa to search for the sword that matches the shield Arisa and Weasel recently discovered. Legend says that together these objects hold the power to the whole kingdom of Deorthas. As Arisa's search progresses, however, she realizes she may be in danger from a deadly stranger. Worse -- she and her friends may be in even graver danger from someone they know all too well.
