The Big Three kids introduce Earth's mightiest heroes to mythology, a happy story in which no one is dead and everyone is confused. Featuring Solangelo and gender-fluid Loki, because yes. Very little angst and lots of smiling and shenanigans.

Piper, Hazel, Nico and Leo run into trouble and then quite literally the Avengers. After being set a long quest, join the demigods as they join the mortal world and hopefully somewhere down the line, save it.
