So here's the deal. There is a full blown rape scene in this book that is written off as romantic, and no one seems to care about it. Marguerite, while in control of someone else's body, has sex that results in a pregnancy. She only ever feels minor guilt about this, and the guilt revolves more around "stealing" her first time with Paul rather than the act itself.
The book goes out of its way to seemingly say that it's ok, because the main Marguerite has looked at some of this universes version of Marguerite's art work and that shows how in love she is with Paul. Yeah, that doesn't count as consent. That's fucked up.
