Homophobia's just one form of abjection, and wherever you have a marker of deviance - skin colour, gender, gender identity, disability - you get the same mechanisms of prejudice.
I started thinking about the endless bullshit about quotas, and how certain types of character are fine "as long as it's important to the story," and so on, started thinking about the absence of the abject.
With undead armies, psychotic angels and exploding airships, Scar Night is a gripping, ripping yarn which rattles along at a great pace. Tether all that to the knock-out image at the heart of the novel-Deepgate, a Gothic city built on a network of chains over a great abyss-and you have urban fantasy at its best.
