Three lives collide, not one of them will emerge unchanged - the exhilarating new novel from the author of the Patrick Melrose series.

When Olivia meets a new lover, Francis, just as she is welcoming her dearest friend Lucy back from New York, her life expands dramatically. Her connection to Francis, a committed naturalist living off-grid, is immediate and startling. Eager to involve Lucy in her joy, Olivia introduces the two - but Lucy has news of her own that binds the trio unusually close.

Over the months that follow, Lucy's boss Hunter, Olivia's psychoanalyst parents, and a young man named Sebastian are pulled into the friends' orbit, and not one of them will emerge unchanged.
