Fugue in Ursa Major

Jake is young, and his life seems boring. Phaedrus is old, and his life seems empty. Phaedrus seems to think that a nightmare is about to happen. Jake just wants to go on dreaming. Does Phaedrus really know something? Or is he just a broken old man? Jake must choose. If Phaedrus is right, then Jake's life is going to change, and Jake will have to rethink everything he ever knew.
