The M.D.'s Mistress

Rebecca, a nurse, travels to a medical facility in a small village in Africa. She’s sent there with Seth, a handsome but foulmouthed and arrogant doctor. They’ve never gotten along, but Rebecca has always been attracted to him. In Africa, Rebecca collapses after wearing herself out, and when she returns to the US to recover, a mysterious billionaire invites her to convalesce at his mountain lodge. At first, she’s overwhelmed by the luxurious villa, but she soon finds herself feeling bored. That is, until Seth suddenly shows up! Source: Harlequin
