Ida is a forty-year-old architect, single and starting to panic – all she sees are other people's children, everywhere.

On a family holiday in the idyllic Nowegian countryside, she's rapidly regressing, picking fights with her sister Marthe and flirting with Marthe's husband. But when some supposedly wonderful news from Marthe sends tensions rocketing, Ida is forced to finally recognise that there's more than one way to grow up.

Funny and unexpectedly devastating, Grown Ups is for anyone who has ever felt the fear of being overtaken and who has had to mark out new milestones of their own.
