Summer has arrived in the Cornish town of Mount Polbearne and Polly Waterford couldn’t be happier. Because Polly is in love: she’s in love with the beautiful seaside town she calls home, she’s in love with running the bakery on Beach Street, and she’s in love with her boyfriend, Huckle.

And yet there’s something unsettling about the gentle summer breeze that’s floating through town. Selina, recently widowed, hopes that moving to Mount Polbearne will ease her grief, but Polly has a secret that could destroy her friend’s fragile recovery. Responsibilities that Huckle thought he’d left behind are back and Polly finds it hard to cope with his increasingly long periods of absence.

Polly sifts flour, kneads dough and bakes bread, but nothing can calm the storm she knows is coming: is Polly about to lose everything she loves?
