Disabled Demigods

This happens after the most recent books; no, it does not have Percy in it, sorry:)
A group of four demigods has been chosen to go on a quest to find a lost god and communicate with them, or more like a bargain so that war doesn't happen. Just another day at camp half-blooded, Right? Well, three of the four demigods are disabled. Soliel, an autistic daughter of Hephaestus, has sensory issues, issues reading emotions, and, without much warning, will go nonverbal. Ruelle is a Daughter of Hecate with cerebral palsy and drop seizures. And finally, Briar Gale, Child of Aeolus, a wheelchair user with a fainting disorder. And the fourth is the perfectly fit son of Ares, Kowen, a physical powerhouse with no education on disabilities. This should be chaos!
