Dani was the only designer worthy of the piece…and the woman he wanted in his bed. Boardrooms & a Billionaire Heir Jake Vance was dangerous, a charming corporate raider. He’d set his sights on Australia’s richest diamond dealers and Holly Mc Leod was given the job as his assistant. She was shocked when her new boss proposed marriage…to her! Jealousy & a Jewelled Proposition Ever since their one night together, making love to Rachel Kincaid was all Matt Hammond thought about. That and destroying the Blackstone diamond empire. The billionaire always got what he wanted, but now did he want sweet revenge…or sweet Rachel’s love?
