The Mark of Athena

The third exciting entry in Rick Riordan's best-selling Heroes of Olympus series is now a graphic novel!
In The Son of Neptune, Percy, Hazel, and Frank met in Camp Jupiter, the Roman equivalent of Camp Half-Blood, and traveled to the land beyond the gods to complete a dangerous quest. The third book in the Heroes of Olympus series will unite them with Jason, Piper, and Leo. But they number only six—who will complete the Prophecy of Seven?
With old friends and new friends joining forces, a marvelous ship, fearsome foes, and an exotic setting, The Mark of Athena promises to be another unforgettable adventure by master storyteller Rick Riordan.
Rick Riordan's Percy Jackson and the Olympians will soon be a series on Disney+.
