Summary:
When shimmer begins to vanish from the rainy city of Seattle, Queen Amalthea and the Soleya Mermaids are called to help.
They discover a chilling truth: three mysterious sisters-Verusha, Nixie, and Calistra-are stealing talents through cursed mirrors and shimmer-draining touch. Known as the Gloomsisters, they cast a fog of fear and forgetfulness over the city.
But the mermaids aren't alone. Deep in the forest, two ancient shimmer wolves-Chloe and Brenan-rise to guide them. Together, they unravel a secret: the Gloomsisters weren't always villains. They were once gifted girls who lost their way.
With courage, shimmer, and a chant of truth, the Soleya Mermaids must help Seattle remember what was stolen-and help three lost sisters find their way home.
A magical tale of memory, talent, healing, and hope.
