Haunted by a past she can't escape, Laura Cunningham desires nothing more than to keep her world small and precise - her quiet relationship and growing jewellery business are all she needs to get by. Until the day when Rob Blake walks into her studio and commissions a necklace that will tell his enigmatic wife Cat's life in charms. As Laura interviews Cat's family, friends and former lovers, she steps out of her world and into theirs -- a charmed world where weekends are spent in Verbier and the air is lavender-scented, where friends are wild, extravagant and jealous, and a big love has to compete with grand passions. Hearts are opened, secrets revealed and as the necklace begins to fill up with trinkets, Cat's intoxicating life envelops Laura's own. By the time she has to identify the final charm, Laura's metamorphosis is almost complete. But the last story left to tell has the power to change all of their lives forever, and Laura is forced to choose between who she really is and who it is she wants to be.
