This one didn't sit well with me. It's too rapey, too obedient, too much "what will other people think of me?".
I expected a strong female character, but to me Elena wasn't so convincing. Maybe it was the "look at me, I'm the only woman here", maybe it's the all too familiar "female character who isn't allowed female traits". Might even be that shape changers aren't exactly my favourite type of "monster". I don't know, but this one isn't it.
