Tamsyn Muir's Locked Tomb books are basically a series of Gothic novels set in a decadent and moribund (and Goth) space empire. It's very canon queer. Also very goth. There are, in fact, lesbian necromancers, and also sword lesbians, and even a few heterosexual male necromancers (I think.)

Wren, out loud to their monitor: ....you have my attention. XD

(so i'll put the books on the to-read list to keep company with the rest)

Question, tho: are they HORROR, or just ... goth as fuck?
