Firstlife, another book that I liked, showed the heroine Ten how not only was she abandoned by her parents, she was locked up by them in an asylum. The other adults in that book are equally idiotic, what with the parents of one girl in the asylum selling her out to the highest bidder. Of course the teenagers then become misfits. And of course some of them become heroes in the end, despite what they went through and how they were let down by the people they should've trusted the most.
