Percy Jackson reaches Camp Jupiter, a camp for Roman demigods, remembering little beyond his name and pursued by monsters that keep returning after he kills them. His new companions have their own unanswered questions: Hazel has returned from the dead, and Frank doubts his abilities without knowing who his divine father is. Together they set out to free Death, whose captivity has disrupted the natural order.

About the authors
Robert Venditti
Robert Venditti is an American comics writer whose career spans original work, major superhero properties, and graphic adaptations of popular prose series. He became known through the Top Shelf title The Surrogates, later adapted as a film, and through his work on Valiant’s X-O Manowar. At DC Comics, his credits include The Flash, Green Lantern, Justice League, Hawkman, and Superman ’78, reflecting sustained experience with established characters and action-driven serial storytelling. Venditti has also adapted Rick Riordan’s Percy Jackson & the Olympians and The Heroes of Olympus novels into graphic form. These adaptations use direct, dialogue-led pacing to condense elaborate quests while retaining their central relationships and mythological settings. Across these assignments, he moves between original concepts and inherited fictional worlds, organizing large casts and expansive fantasy or science-fiction premises around clear conflicts and character-centered adventure. Six Days, inspired by his uncle’s participation in D-Day, brings a personal historical subject into that broad body of work.
Rick Riordan
Rick Riordan writes fast-moving fantasy adventures that place ancient mythology inside contemporary adolescent life. His direct, conversational prose relies on witty dialogue, brisk reversals, and quest structures that keep large casts and elaborate supernatural conflicts legible. Identity is often both personal and inherited. His young demigods must understand their powers, families, and loyalties while navigating prophecies, rival camps, and wars among gods. The Lightning Thief establishes this method through Percy Jackson, a troubled schoolboy who discovers that Greek myth describes a hidden living world and that Poseidon is his father. Later books broaden the design without abandoning its clarity. The Lost Hero introduces three new protagonists through Jason’s missing memory and a rescue mission, while The Son of Neptune alternates among Percy, Frank, and Hazel as Roman traditions complicate the series’ mythology. Before Percy Jackson, Riordan wrote the Tres Navarre mysteries for adults, an earlier sign of his interest in suspense, investigation, and tightly managed plots.
