Apollo must head to the American Midwest where, rumour has it, a haunted cave may hold answers. There are a few things standing in his way though. The cave could kill him, or drive him insane.
Oh, and a Roman Emperor, whose love of bloodshed makes Nero look tame. To stay alive, Apollo needs the help of a mortal goddess, a bronze dragon, and some familiar faces from Camp Half-Blood. Will he survive the greatest challenge of his four thousand year existence? __________More books by Rick Riordan:The Percy Jackson series:Percy Jackson and the Lightning ThiefPercy Jackson and the Sea of MonstersPercy Jackson and the Titan’s CursePercy Jackson and the Battle of the LabyrinthPercy Jackson and the Last OlympianPercy Jackson: The Demigod FilesThe Heroes of Olympus series:The Lost HeroThe Son Of NeptuneThe Mark of AthenaThe Heroes of Olympus: The Demigod FilesThe Kane Chronicles series:The Red PyramidThe Throne of FireThe Serpent’s ShadowThe Magnus Chase Series:Magnus Chase and the Sword of SummerMagnus Chase and the Hammer of Thor Magnus Chase and the Ship of the Dead
