From the World of Percy Jackson The Sun and the Star

Nico di Angelo, intimately acquainted with the realm of the dead due to his lineage as Hades' son, becomes troubled when a distressed voice invades his dreams. Believing that this voice stems from the Underworld, Nico suspects it belongs to Bob, a Titan who has turned over a new leaf. A foreboding prophecy then confirms Nico's suspicions—Bob is in need of help, and it falls upon Nico to save him. Naturally, Nico's partner, Will Solace—the son of Apollo, the god associated with light—insists on accompanying him on this daunting mission. However, a question lingers: Can Will endure the world's darkest recesses? Furthermore, what consequence lies in the prophecy suggesting Nico must sacrifice something equally valuable? As Nico wrestles with both inner and external demons, his bond with Will faces a formidable trial. Will their love endure amidst such gloom? Arriving in September 2023, "Percy Jackson and the Olympians: The Chalice of the Gods" presents a thrilling new escapade featuring the beloved characters from "The Lightning Thief."
