Honestly, a lot of goblin books I see lately miss what made them interesting in the first place—they’re too cute or too obviously a human allegory. The older stuff where they’re genuinely a weird, nasty, and clever adversary hits different. A real standout is ‘The Spider’ by Leo Carew, which has this brutal, tactical faction of goblins with their own grisly culture, not just mindless cannon fodder. It feels like reading about a pack of hyenas engineered for war.
There’s also a short story collection edited by J.R. Rain, ‘Goblins’, which is hit-or-miss but has some truly bizarre and fun takes. A few authors there remember that goblins should be unsettling, not just comic relief. I found a forgotten gem from ages ago, ‘The Grey Horse’ by R.A. MacAvoy, which isn’t goblin-centric but features a sidhe creature with that same trickster malice. It’s the sort of thing you stumble on and wonder why it isn’t talked about more.
