Imogen Tolliman and Gray Adams can't wait to get married after getting engaged the previous year, when they were stranded by snow in a blizzard. Now they are busy planning their wedding, but when the date slips six months because Gray is working on a huge film project, it seems like fate that after their snowy start, they will end up getting married at Christmas. The couple are living in Immi's grandfather's picturesque lock-keeper's cottage at the Aysbury marina in the Cotswolds, which they are renovating to become their forever family home. As well as building work, full-time jobs and wedding planning, Immi is in charge of raising money to build a children's playground, to celebrate the tenth anniversary of The Santa Ahoy Cruises - her grandfather Tollie's life work. When Gray is suddenly forced to travel abroad, Immi is left to cope with everything alone, and before long, even the best-laid plans start to wobble. When a terrible betrayal is uncovered, the whole community of Aysbury is left reeling, and Immi is left wondering if there will be a wedding after all...
