Enjoy “Ponies,” a short story by Kij Johnson and the winner of the 2010 Nebula Award for Short Story.
The invitation card has a Western theme. Along its margins, cartoon girls in cowboy hats chase a herd of wild Ponies. The Ponies are no taller than the girls, bright as butterflies, fat, with short round-tipped unicorn horns and small fluffy wings. At the bottom of the card, newly caught Ponies mill about in a corral. The girls have lassoed a pink-and-white Pony. Its eyes and mouth are surprised round Os. There is an exclamation mark over its head.
The little girls are cutting off its horn with curved knives. Its wings are already removed, part of a pile beside the corral.
