What this book is about

Gideon Nav is a swordhand for Harrowhark, a necromancer competing for divine power in a dying solar system, as the nine houses of the empire converge on a crumbling mansion where everyone is murdering everyone else. Tamsyn Muir's debut is wildly original—part murder mystery, part bone magic, entirely queer—and genuinely funny until it isn't.
