All or NothingIf she's not good enough for all of him, she'd rather have none.Forty-one-year-old Hector Kelly has lived the BDSM lifestyle all his adult life, but the recent influx of inexperienced and starry-eyed young women has killed its luster for him. When he reluctantly accompanies his best friend to The Dark Cellar during an open night, he is not surprised when he has to rescue a clueless young woman from a predatory Dom. Against his better judgment, he spends the rest of the night showing the gorgeous Amber around the club.Until she entered The Dark Cellar, twenty-one-year-old Amber Sommerville was convinced BDSM only existed between the covers of her favorite romance novels. As Hector introduces her to this unknown world, everything she sees awakens desires she's never experienced before.The attraction between Hector and Amber is as instant as it is undeniable. But with an almost twenty-year age difference between them and Hector's conviction that Amber is too young both for him and to know whether or not she wants to submit, their developing relationship remains purely vanilla-for the most part. When Amber witnesses Hector in full Dom mode, she recognizes that he's been holding back and sets him an ultimatum: either he fully commits all of himself to their relationship or she'll leave. If Hector wants to hang on to the woman who has captured his heart, he'll have to reassess his preconceived notions.
