Unfortunately for him the quest is particularly difficult, mostly because Gaia wants him for some unknown reason and has sent her army to capture him.

Danger is around every corner for Nico, read the story and find out if he manages to pull through. DISCLAIMER: I don't own Percy Jackson or any of the characters other than my own.
