    Shock Greek Heir by Lynne Graham

    He lost his memory…and gained an heir!

    Running the family empire means Sebastian quitting his playboy lifestyle. Cue the perfect detox: a week at sea, far from temptation. The hitch? Irritatingly alluring crew member Bunny! Fortunately, she seems equally determined to ignore their chemistry… Until an accident strips Sebastian of his memory, obliterating his last defence against their desire. But passion indulged in paradise has real-world consequences—Bunny’s pregnant!

    Christmas Eve Ultimatum by Jackie Ashenden

    Tis the season to spend in the Greek’s bed…

    At CFO Katla’s company Christmas Eve party, Ulysses delivers an ultimatum: she'll spend six months with him or he’ll ruthlessly take over her business. With him, she feels things she’s never felt before. Not even with the ex who betrayed her. Even contemplating Ulysses’s demand unleashes a reckless, raw need inside her. And once Katla accepts their desire, she knows there’ll be no going back…

    His Pregnant Enemy Bride by Michelle Smart

    Wed for her secret on the enemy’s terms…

    The Tsalikis and the Antoniadises are the most powerful of families and the bitterest of rivals. Knowing she’ll be disowned for carrying Alexis Tsaliki’s one-night heir, Lydia realises a wedding ring is her only guarantee of security for her unborn child. All she wants is a union on paper, but the billionaire counters… If Lydia becomes his wife, she must share his name and his bed!

    Unwrapping His Forbidden Assistant by Lorraine Hall

    A white Christmas…turned red-hot!

    Billionaire Diego doesn’t do festive cheer. He’d rather be alone in the Italian Alps with his grief and his survivor’s guilt. Until previously hands-off PA Amelia Baresi tracks him down and demands he resurrect the Folliero holiday party tradition. It should be an easy no. If only she wasn’t so persuasive—and if only the heat between the boss and his assistant wasn't quite so tantalisingly illicit…
