Holly Madison never set out to be a wedding planner. She was just helping her stressed sister Lila with cakes and décor for her big day. But when Lila and Jack's summer ceremony is a runaway success, with high-profile guests raving about the food and styling at the pretty treehouse venue, word about Holly's expertise soon spread. A year on, Holly has a fast-growing business on her hands, and she is struggling to keep up. Boyfriend Marco worries that with so little experience she could be heading for a fall. After all, Holly's clients expect the very best - she's promised lawyers Mia 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, will she be able to deliver?
