Fiona Clutterbuck thinks she’s got it all when she finally becomes Mrs. Brian Goodchild, marrying weeks before her 30th birthday. But when he abandons her at the altar, she does the only thing she knows how to do, run away.

Crashing the honeymoon camper van, she finds herself in the middle of nowhere on the west coast of Ireland with only the clothes she’s stood up in. So, if she’s not Mrs. Brian Goodchild anymore, who is she? One thing she does know, she can’t go home. What Fi wants is to hide away, and where better?

She takes a job on an oyster farm despite being terrified of water and her new boss, the wild and unpredictable Sean Thornton and his oyster broker partner Nancy Dubois. There, she battles oyster pirates, pearl queens and circling sharks before finally coming out of her shell and finding love amongst the oyster beds of Galway Bay.
