In The Fountain of Essomuai, the third book of the Shapewalker's Song series, Sumi is still far away from home. Only now, she knows Essomuai is real, and she can feel the goddess calling to her from the south. But if one legend proved true, how many others will she have to face in Vilodai's Heart? With both Erso and Parimu in tow, they head first to Ekosinar, the legendary seafaring kingdom, in hopes of finding someone who can take them to the mountains. Their alliance is fresh and uneasy, but if she finds the power she needs, there's still a chance she can make her way home, to change Berill and everything else with it.
