Nico di Angelo is known for many things. The only son of Hades, the half-blood who helped the seven, and not to mention being the boy who had a crush on Percy Jackson.

On this Cassandra Clare worthy plot twist story ((if I do say so myself)) you shall see how each side shall reacted when introduced to one another. And how Nico fits in perfectly in the middle of the two worlds.
