The Sun and the Star: A Nico di Angelo Adventure

In this gripping tale co-written by New York Times #1 best-selling author Rick Riordan and award-winning novelist Mark Oshiro, demigods Nico di Angelo and Will Solace must brave the horrors of Tartarus in order to save an old friend.

Nico di Angelo, the son of Hades, has experienced a great deal in his life, including the untimely deaths of his mother and sister, being forced to come out as gay, and losing his companion Jason during Apollo's trials. However, Will Solace, the son of Apollo, who happens to be his lover, is a genuine bright spot in his life. The two gods can defeat any adversary or barrier together. That has been the situation so far, at least.

Nico is being tormented by a voice that seems to be calling to him from Tartarus, the lowest realm of the Underworld. He believes he knows who it is: Bob, a transformed Titan who Percy and Annabeth were forced to leave behind when they fled Hades' domain. It's clear to Nico from both his visions and Rachel Dare's most recent prophesy that Bob is in danger. Nico cannot back out of this journey, no matter how much Mr. D and Chiron protest. Naturally, Will is adamant on accompanying. However, is it possible for a light-based entity to endure in the world's darkest region? Furthermore, what does it indicate by the prophesy that Nico must "leave something of equal value behind"?

In this stand-alone adventure starring two of the most beloved characters from the Percy Jackson epic, Nico will have to fight both internal and external demons as his relationship with Will is put to the ultimate test.
