Ever since Soren was kidnapped and taken to the St. Aegolius School for Orphaned Owls, he has longed to see his sister, Eglantine, again. Now Eglantine is back in Soren's life, but she's been through an ordeal too terrible for words. And Ezylryb, Soren's mentor, has disappeared. Deep within Soren's gizzard, something more powerful than knowledge tells him there's a connection between these mysterious events.
In order to rescue Ezylryb, Soren must embark upon a perilous quest. It will bring him face-to-face with a force more dangerous than anything the rulers of St. Aggie's could have devised - and a truth that threatens to destroy the owl kingdom.
Ezylryb is still missing. Soren is searching the sky for him as he's been doing for two months. A comet flashes through the sky and Octavia comments that it might be an omen. Soren later has a nightmare about flecks. During a weather interpretation flight, the chaw stops in the Spirit Woods where Soren meets the scrooms of his parents who tell him to beware Metal Beak. When Soren gets back to the Tree, he asks Bubo about Metal Beak and Bubo tells him that he's the most brutal and evil owl on Earth. He also tells Soren about a Rouge Smith in Silverveil. Soren tells the other members of the Band, which now includes Eglantine, and they agree to go out to find the Rouge Smith of Silverveil during the Harvest Festival. Eglantine goes to find Mrs Plithever who conforts her. After everyone gets into a party induced stupor, the Band takes off for the take off spot. Eglantine arrives late with Primrose. Primrose wants to come with the Band as thanks for Soren's kindness. Soren tells Primrose and Eglantine they can't come because they're not ready and leaves with the rest of the Band.
The Band arrives in Silverveil and meet the Rouge Smith who they learn is Madame Plonk's sister. She tells the Band that Metal Beak and his gang are worse than St Aggie's and that Ezylryb does have enemies and that Octavia wasn't born blind. When they get back to the Tree, they find that their absence had been discovered by Dewlap, who Twilight had to do a flintmop for. Soren, Gylfie, and Digger sneak into Ezylryb's hollow where they find a secret room that has a pair of battle claws inside. Octavia appears and tells them that Ezylryb was once Lyze of Keil, the legendary warrior from the Northern Kingdoms who all but ensure the Keilian League's victory in the War of the Ice Claws. She also tells them that she's a Keilian Snake and about Ezylryb's mate Lil and his brother Ifgar and how he is responsible for her and Ezylryb's mutiltions: Ifgar had loved Lil but she had chosen Ezylryb. So he became a turnfeather and betrayed not just Ezlryb but also the entire Keilian League by joining the League of the Ice Talons on the condition that Lil be given to him as a mate. In the Battle of the Ice Talons, Lil was killed and Lyze went yeep he was caught by a talon injuring it to the point where he later bit it off. It was during the same battle that Octavia was blinded.
When the trio return to their hollow, they find Eglantine restless. With the help of issenglass, Eglantine reveals the existance of the Tytonic Union of Pure Ones of which Metal Beak is the leader of. Otulissa flies in and offers to come with them. Soren agrees and declares the Band's reorganization into the Chaw of Chaws. They arrive at the Pure Ones castle and learn that the power of flecks is the power of higher magnetics. Otulissa reveals the need for mu metal and that Ezylryb is trapped by a devil's triangle. With the help of a coal and mu metal the Chaw of Chaws destroys the Devil's triangle and frees Ezylryb. Suddenly, they are attacked by Metal Beak and nine of his followers. Martin and Ruby show up and help drive them off. During the battle, it is revealed that Metal Beak is Kludd. After the battle, the Chaw of Chaws heads back to the Tree with Ezylryb, who is warmly welcomed back.
