I have not read it, but I am a fan of both of those creators, so I am sure I will read it as soon as I get a chance!
But I don’t think they are ‘following my lead,’ putting trans characters in books is just a long-overdue course correction that I hope a lot of creators are thinking about. I don’t feel like anyone’s ‘leading,’ we are just trying to catch up a little bit after being so ridiculously behind. The more diversity in characters, the better, we have a LOT of catching up to do!
