Some people are romantics. Some aren't. When Sophie and Maddie are summoned to a mysterious, top-secret meeting by their best friend Kate's partner, and told that he's planning to whisk Kate away for a surprise wedding in Gibraltar, it's immediately clear that bubbly florist Sophie is a total romantic. And that freewheeling, purple-haired Maddie is not.

Soon, Maddie finds herself reluctantly organising venues, planners and ceremonies; trying not to think of her own memories of Andalucia, and those she's lost touch with there. Meanwhile Sophie's hoping this dreamy gesture might spur on her own boyfriend to similar plans . . . and absolutely not thinking at all about Kate's gorgeous brother-in-law-to-be.

But Kate's got no idea what's going on. And as the stresses pile up and the group jet off to the sunny south, it seems it's not just Kate who might get a surprise in Spain - one that could change everything . . .
