Hazel never set out to be a wedding planner. She was just helping her stressed sister Lila with cakes and decor for her big day. But when Lila and Ollie's summer ceremony is a runaway success, with guests raving about the food and styling at the pretty venue, word about Hazel's expertise soon spreads. But Hazel's clients expect the very best - she's promised lawyers Gemma and Eliot a snow-covered castle in the Scottish Highlands, and laidback couple Josh and Sarah a bohemian beach wedding in a Caribbean paradise. But as weather, in-laws and wilful brides conspire against her, can Hazel get two very different couples to walk up two very different aisles to say 'I do'? And will she find her own happy ending if she does?
