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 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 - a truth that threatens to destroy the owl kingdom.
