"I can still recall how cold the pearls felt on my bare neck as Mr Fitzroy secured the clasp, and how heavy they were. I also remember that they were far, far too long for me. But, oh how mesmerising I found those pearls..."

Sophia Beaumont-Brown was an IT girl. But now she's in the papers for all the wrong reasons. Single, sofa-surfing and not speaking to her family, only her grandmother has any faith left in her. From her hospital bed, Tilly Beaumont sends Sophia letters about her life: dispatches about wartime England, about family secrets and finally, about the most beautiful thing she ever owned - a necklace of the most incredible pearls.

If Sophia's prepared to listen, she'll unlock the secret story of generations of incredible women, from the pearl divers of Japan, to high society in pre-war England, and find that the necklace has changed the lives of all who have worn it. The only problem? No one knows where it is.

Sophia must find out if she's ready to take on the search for something so perfect it can change a life. Wouldn't a girl do anything to hold that in her hands?
