It's about that level of awful but easier to take because it's prose, but worse because it's a kid who lacks a support system?

I'm a third of the way through and nothing particularly bad has happened to the lesbian space necromancers other than they have to deal with each other and are teenagers. I don't think it's the kind of book where bad things happen on account of them being lesbians but presumably bad things happen on account of them being space necromancers (or not; I'm not unconvinced that this isn't just going to be a straight-up romance).
