In a world of sprawling, sentient deserts, where the people live in harmony with the sand, Anya, a young sand sculptor with the ability to manipulate the sand, sets out to find the Sand Heart, a mythical artifact capable of controlling the very flow of the sand. Her journey takes her across treacherous dunes, encountering rival tribes, ancient sand spirits, and the enigmatic Sandborn, beings born from the very essence of the desert. Anya's past, marked by a tragic sandstorm that buried her village, reveals a connection to the Sand Heart that could either bring prosperity to the desert or unleash a devastating sandstorm that could bury the entire world.
