Abyss published Koja’s next novel, Bad Brains, about an artist whose sustains a minor head injury at a party that unleashes apocalyptic hallucinations, seizures, and extradimensional silver snot dripping over everything he sees. Then his paintings start coming to life. Relentlessly interior, unfolding in dreams, visions, and nightmares, reading the book is like being trapped inside William Blake’s worst headache.
