It's interesting, but it's not for the faint heart.
Actually, I guess you are right, since it becomes "legal" once the parents have signed the child's rights away to a 3rd party.
It's a real shame that signing away your child's rights, without them present in a court of law, is not illegal.
I read 20 chapters of this before I realized it wasn't fiction! This is crazy.
