Jazz is finding it difficult to fit into her new school, and her love of surfing seems destined to be quashed for ever. Not only do Brighton's beaches have stones instead of sand and the water is downright freezing.

but there's not a surfboard in sight. When she meets her older cousin, Amber, at a family dinner in London. Amber senses Jazz's unhappiness and tells her about the Moonlight Dreamers, a secret society of likeminded friends that she founded years earlier.

Amber suggests that Jazz seek out a group of soulmates too and form her own Moonlight Dreamers. At first Jazz is wary, but then decides to leave postcards for prospective soulmates, just as her cousin had. And so a new group of Moonlight Dreamers is born.

Allegra, Hope, Portia and Jazz may be very different but they soon become firm friends who are always there for one another. They listen to each other's problems and support each other's hopes – and help them make their dreams come true.
