La profecia del llamp i les estrelles

Nico di Angelo, son of Hades, has overcome the most difficult tests that could have been imagined: from the death of his mother and sister to losing his friend Jason during the trials of Apollo. But now there is a ray of sunshine in his life: Will Solace, the son of Apollo. Together, the two demigods can overcome any obstacle. At least, that's how it was until today. Now a voice calls Nico from Tartarus, the lowest part of the Underworld. He is clear about his mission, but Will is not going to let him go alone... The question is: can a being made of light survive in the darkest part of the world? Will he be able to overcome the demons around him and those within him?
