In George R. R. Martin's award-winning novella, telepathic lovers Robb and Lya travel to the planet Shkea to investigate a strange local religion. The native Shkeen willingly allow a parasite to consume them in an act of ultimate union they call 'The Joining.' While Robb remains skeptical and disturbed by the practice, Lya becomes increasingly drawn to the profound sense of connection and love it offers, creating a deep rift between them as they confront the very nature of love, loneliness, and faith.
