Tempt Me With Diamonds

Description for TEMPT ME WITH DIAMONDS by Jane Feather:

Three friends who met at an elite English boarding school take on the town -- and the ton -- one by one, in this sparkling new series about love, loss, and lustrous gemstones, from New York Times bestselling author Jane Feather...

A FINE ROMANCE…
Diana Sommerville seems to have it all -- beauty, brains, and vast wealth, thanks to her family's ownership of a diamond mine abroad. But when her beloved brother dies in battle and leaves a lion's share of his estate to his best friend, Diana finds herself in a situation that seems scripted for the stage: Sharing her family home with the man she used to love -- and now loathes. Worse, her unfaithful former fiancé has already moved in...

OR AN EXCELLENT FAKE?
Rupert Lacey didn't expect Diana to take the news without a fight. Still, he didn't expect her to bring the battle directly to their newly shared doorstep -- complete with a full set of trunks, and a full set of orders to the staff. Yet there she is, bold, regal ... magnificent as ever. Now they would face a formidable challenge: to ignore each other -- and the unanswered questions that stood between them. The only sure thing is their still blazing desire. But with a woman like Diana, it will take nothing less than a momentous misunderstanding, a missing prized mare, and a shocking revelation to restore a love that hasn't lost its shine...

This is #1 in London Jewels Series.
