~Gideon the Ninth by Tamsyn Muir ~

Gideon is a useless lesbian/wonderful swordswoman. Harrow is a Hermione-if-she-was-in-Slytherin necromancer. Together, they must solve the mysteries lurking in a gothic mansion. The problem is they hate each other. But also they definitely love each other. Mostly, they are obsessed with each other and we are obsessed with them.
