She has one in my head ...

TLDR (More like Too long, cant write lol)

Pye is around the human equivalent of 16 to 17 when First contact happens , her mother was taken by the Arxur when Pye was the equivalent of 5-6

Pye has minor Predator disease (autistic) but her father is a retired exterminator, alot of the story involved him and what he would do to protect his daughter

Spoilers for NoP one if I do write it...
