GOD I love this so far!
There's just two small errors I saw:
1. The {boy/girl/kid} choice is visible in this passage,
"Gabe scratched his double chin. “Maybe if you hurry with that seven-layer dip. And maybe if the {boy/girl/kid} apologizes for interrupting my poker game.”"
2. If you're a child of Hades, the dream still mentions that you're at the edge of the surf, despite being in a cemetery.
"It was storming in a cemetery, and three beautiful animals, a white horse, a golden eagle, and an obsidian black dog were trying to kill each other at the edge of the surf."
I'm really looking forward to seeing more of A and meeting M and V!
