When 29-year-old Annie Trebarwith receives an unexpected letter from a great-aunt she’s never known, she leaves her shoebox-sized flat in London and catches a train to the rugged Cornish coast. Salt Bay is beautiful and Annie begins to kindle a bond with her great-aunt Alice. Even though there is zero phone signal and the locals – including the gorgeous but brooding Josh Pasco – can be decidedly grumpy at times, Annie starts to feel at home in Salt Bay. Soon Annie’s love of music leads her to relaunch the Salt Bay Choral Society, and she’s surprised to see how just much the choir means to the community – and she even starts to break through Josh’s surly exterior… But London is calling Annie back, and she has to make a decision. Give up her old life completely, or leave Salt Bay, her new-found family – and the choir – behind?
