Overwhelmed by the huge success of her latest novel, exhausted and suffering from a crippling inability to write, Delphine meets L. She embodies everything Delphine has always secretly admired: feminine sophistication and spontaneity and an uncanny knack of always saying the right thing. L. senses Delphine's vulnerability and slowly but deliberately carves herself a niche in the writer's life. As their lives become more and more entwined, L. threatens Delphine's identity, both as a writer and as an individual.
