The House Of Hades (Official Cover)
"Annabeth and Percy attempt to travel through Tartarus to defeat Gaea’s forces and close the Doors of Death from Tartarus’ side. Jason, Piper, Hazel, Frank, Leo, Coach Hedge and Nico travel with the Athena Parthenos and must close the Doors of Death at The House of Hades, an underground temple in Epirus, Greece, the location of the Doors of Death in the mortal world and save Camp Half-Blood from being attacked by Camp Jupiter. Rick Riordan stated that there will definitely be some scenes from Tartarus. However it is uncertain if this means through the demigod dreams or through Percy or Annabeth’s eyes. via Wikipedia “
Percy and Annabeth fell into the pit leading straight to the depths of the Underworld which also leads them to the other side of the Doors Of Death. Piper, Jason, Leo, Frank, and Hazel are assigned to close the mortal side of the Doors with the guidance of their companion, Nico.
If Percy and Annabeth defeated Gaea’s Forces and be able to close the Doors of Death with the others, How will they be able to escape?
