You’ve never seen Tartarus quite like this before! Think you can handle the horrors of the Underworld rendered in full color? Mark your calendars, demigods. The Heroes of Olympus Book 4: The House of Hades: The Graphic Novel will be released 9/24/24. Check out the exclusive cover reveal for this all-new adaptation and read the first plot synopsis below:

The fourth installment in the New York Times #1 best-selling Heroes of Olympus series from Rick Riordan, author of Percy Jackson & the Olympians, will soon be available as a graphic novel! Text adapted by New York Times best-selling author Robert Venditti and illustrations by New York Times best-selling graphic novelist Orpheus Collar.

At the conclusion of The Mark of Athena, Annabeth and Percy tumble into a pit leading straight to the Underworld. The other five demigods have to put aside their grief and follow Percy’s instructions to find the mortal side of the Doors of Death. If they can fight their way through the Gaea’s forces, and Percy and Annabeth can survive the House of Hades, then the Seven will be able to seal the Doors from both sides and prevent the giants from raising Gaea. But, Leo wonders, if the Doors are sealed, how will Percy and Annabeth be able to escape?

They have no choice. If the demigods don’t succeed, Gaea’s armies will never die. They have no time. In about a month, the Romans will march on Camp Half-Blood. The stakes are higher than ever in this adventure that dives into the depths of Tartarus.
