From the author of the Pegasus series comes the third book in a spellbinding fantasy series for fans of Rick Riordan and Shannon Messenger, in which Riley must protect her family’s new life in Atlantis. Life in Atlantis has always been unpredictable. But lately, the Community has finally started to feel like the stable home Riley hoped it could be—until the weather becomes anything but stable. After three Red Moons within a month, the latest of which brings an earthquake, it’s clear that something is wrong. But what is causing this change? In addition to creating chaos, the storms are also damaging homes across the territories and escalating tensions between the groups. And when an encounter with the Underwater Territory goes badly, several of Riley’s friends are kidnapped! With no hope of reaching her friends on her own, Riley embarks on a quest—accompanied by Storm, Alfie, Maggie, Pea, and Kevin—to enter the Enchanted Territory and seek the Fairy Queen’s help. But intrigue and secrets abound in Atlantis, and Riley is hopelessly unprepared for the ways that forgotten artifacts and ancient power struggles will disrupt her plans. Riley will have to learn to navigate the magical societies and finally learn the truth behind the island’s history if she is to have any chance at surviving the journey—let alone saving her friends.
