At the beginning of the book, Blue the Silkwing and his sister Luna are preparing for Luna’s metamorphosis. Blue is exited and happy for his sister, but when her metamorphosis starts, Blue and his family are startled to see Luna weaving with fiery silk. Then, Blue sees Hivewing guards take Luna away. Blue’s friend Io tells him that Luna has a rare silkwing condition called Flamesilk. Io also warns Blue that the Hivewings and their queen, Queen Wasp, will try to capture him as well. When Blue tries to escape after Io’s warning, he sees many Hivewings suddenly doing strange things and trying to capture him. He finds out that this is because Queen Wasp can mind-control all Hivewings....Exept for one. Blue soon meets a Hivewing named Cricket, who is immune to Wasp’s mind control. Thanks to Cricket, Blue soon is able to find Swordtail, a friend of Luna. Swordtail, Blue, and Cricket fly to the Wasp hive, where they think Luna is imprisoned. Everything is going well until they get captured by several Leafwings, a tribe that was thought to be extinct. They tell Blue that if he and Cricket will steal the Book of Clearsight for them, they will show him where Luna is. Blue, Cricket, and Sundew (one of the Leafwings) go into the Library where Blue is captured by the Hivewings. He is taken to a cave where he finds Luna and many other Flamesilks. They escape though a hole in the cave, and crawl down a tunnel which leads onto a beach. They peacefully rest on the beach when some Hivewings attack. Luna is blown off into a storm and makes her way to Pyrrhia, where she meets Moon, Quibli, and Jerboa.
