Ida is a forty-year-old architect, single and starting to panic. She’s navigating Tinder and contemplating freezing her eggs, terrified that time has passed her by, silently, without her ever realising it. All she sees are other people’s children, everywhere.

Now stuck in the idyllic Norwegian countryside for a gathering to mark her mother’s sixty-fifth birthday, Ida is regressing. She’s fighting with her younger sister, Marthe, and flirting with her sister’s husband. But when some supposedly wonderful news from Marthe heightens tensions further, Ida is forced to mark out new milestones of her own.

Funny and unexpectedly devastating, Grown Ups is for anyone who has ever felt the fear of being overtaken and who feels almost - but not quite - grown up.
