The Tycoon’s Pregnant Mistress by Maya Banks

Greek hotel magnate Chrysander Anetakis’s former mistress was pregnant? And had amnesia? That meant Marley Jameson didn’t remember betraying him by selling company secrets. Or that he’d thrown her out of his life. So he told her a little white lie: they were engaged. Then he swept her away to his Greek island to await the birth of his baby and enjoy her sudden devotion…before tossing her out.

But he didn’t count on Marley regaining her memory so soon.
