About Nico Di Angelo Adventures
Rick Riordan’s Nico Di Angelo Adventures series gives one of the Percy Jackson universe’s most important supporting characters his own central storyline. Co-written with Mark Oshiro, the series begins with The Sun and the Star and continues with The Court of the Dead, moving Nico di Angelo from the margins of other heroes’ quests into a role where his grief, power, love, and history become the emotional core of the adventure.
Nico has long been one of Riordan’s most layered demigods. As the son of Hades, he carries a natural connection to death, ghosts, shadows, and the Underworld, but his significance has never been only about his powers. Across the earlier Camp Half-Blood books, Nico is shaped by loss, loneliness, displacement, and the difficulty of belonging anywhere for long. His sister Bianca’s death, his time out of step with the modern world, and his struggle to accept himself all leave marks that cannot be brushed aside once he becomes the hero of his own story.
The Sun and the Star places Nico and Will Solace at the center of a quest into Tartarus, one of the darkest and most dangerous places in Riordan’s mythology. Will, a son of Apollo, is in many ways Nico’s opposite: associated with light, healing, music, and warmth. Their relationship gives the series its strongest contrast, but the book is not simply built on a light-and-dark pairing. It is about how two people who love each other can still misunderstand pain they have not personally lived through. Nico’s past is not something Will can fix with optimism, and Will’s care does not make him immune to fear or frustration.
The Tartarus journey also gives the first book a deeper emotional purpose. Nico is not only going somewhere dangerous; he is returning to a place tied to trauma, sacrifice, and unfinished responsibility. The mission involving Bob the Titan, also known as Iapetus, connects the story back to earlier events in the wider Percy Jackson timeline, especially the consequences of promises made and forgotten during war. Riordan and Oshiro use the quest to explore memory, guilt, recovery, and the difficult work of facing darkness without letting it become the whole truth of who Nico is.
The Court of the Dead expands the series by bringing Nico and Will into contact with Hazel Levesque at Camp Jupiter. Hazel, like Nico, is connected to the Underworld through her divine parentage, and her presence gives the story a strong family and legacy thread. The book also shifts attention toward monsters and the question of who deserves protection, compassion, or judgment. That is a natural direction for a Nico-centered series because Nico has often understood what it means to be feared or misunderstood by others.
The Nico Di Angelo Adventures series works best as a more intimate branch of the Percy Jackson world. It still has quests, gods, monsters, prophecies, and danger, but its real weight comes from character healing. Nico is not treated as a side character defined by gloom or mystery anymore. He is a protagonist learning how to live with the past, love openly, and step into leadership without losing the strange, wounded, powerful qualities that made him memorable in the first place.
