In grey, 1930s England, Bea has grown up kicking against the conventions of the time, all the while knowing that she will one day have to marry someone her parents choose - someone rich enough to keep the family estate alive. But she longs for so much more - for adventure, excitement, travel, and maybe even romance.

When she gets the chance to spend the summer in Italy with her bohemian uncle and his fiancée, a whole world is opened up to Bea - a world that includes Ben, a cocky young artist who just happens to be infuriatingly handsome too. Sparks fly between the quick-witted pair until one night, under the stars, a challenge is set: can Bea and Ben put aside their teasing and have the perfect summer romance?

With their new friends gleefully setting the rules for their fling, Bea and Ben can agree on one thing at least: they absolutely, positively will not, cannot fall in love...

A long, hot summer of kisses and mischief unfolds - but storm clouds are gathering across Europe, and home is calling. Every summer has to end - but for Bea, this might be just the beginning.
