Tired of being overlooked by her sisters, the Fates, an immortal girl seeks to rewrite her destiny in the third book in the New York Times bestselling middle grade fantasy series The Underwild.

As the youngest sister of the fates, Eri knows she's expected to quietly gather the wool her sisters spin and snip. But when Eri discovers that a fate-thread her sisters so carefully spun has become unraveled, she slips away to investigate.

Her search leads to Senka and Anya, who are on a quest to return lost memories to ghosts in the Under-Afters throughout the Underworld. Eri convinces Senka and Anya to bring her along with them. But when Senka meets a ghost from her long-forgotten past, Eri notices something is very wrong with their fate-threads and worries that things are not as they seem.

Eri is mystified by the web now connecting Senka to mortals, ghosts, and the gods, for nothing like this has ever been seen before. And when she realizes those tied to Senka are being manipulated by an ancient power, Eri is the only one who can follow the threads to discover who is pulling the strings.
