FROM THE WORLD OF PERCY JACKSON The fourth novel in Rick Riordan’s best-selling Heroes of Olympus series – now as a graphic novel!Lost in the depths of the Underworld, Percy and Annabeth’s lives rest in the hands of their friends and fellow demigods – Jason, Piper, Leo, Hazel and Frank. Unsure if they’ll ever see Percy and Annabeth again, the five must put aside their grief and find the mortal side of the Doors of Death to follow Percy’s final instructions. The doors must be sealed to stop the giants from wakening Gaea, the primordial goddess.

But between them and the door lies a vicious army intent on raising the goddess. If the demigods can fight their way through the army to seal the door – and Percy and Annabeth can survive the House of Hades long enough – the seven might just be able to stop the destruction of Camp Half-Blood. .
