Becca Burnside is going to make this the year she turns her forties around and creates a life her 16-year-old self would be proud of. . . A smidgen of romance wouldn't go amiss either.

Now Becca and Niamh find themselves not only facing the usual problems that come with being women of a certain age they're going to be grannies. So when Becca's new job invites them on a weekend retreat it seems the perfect way to distract themselves from 'the Situation'. But will wild water swimming and yoga be enough to help the women face the biggest challenge of their adult lives? And can their friendship survive the chaos of a new baby?
