The Medusa Frequency by Russell Hoban

A blocked London writer is jolted into a surreal quest when an experimental therapy opens a channel to the speaking head of Orpheus. As myth invades the everyday, he navigates comic and haunting encounters, chasing an elusive muse and a lost love while trying to avoid being petrified by his own fears. The story blends contemporary life, classical myth, and wordplay into a meditation on creativity, memory, and desire.
