His Good Girl by Kira Bloom

When Winter walked in to interview for the position of personal assistant to an acclaimed architect, she never expected to be offered the job right on the spot.
She also didn’t expect her new boss to be drop dead gorgeous.

Dmitry Maslow is sin in a tailored business suit, with a delicious Russian accent that makes Winter’s heart race, and a burning gaze that turns her knees to pudding. The attraction between them is instant and overwhelming, and she’s quickly drawn in by Mr. Maslow’s commanding dominance, his penchant for spanking, and his filthy promises.
But as the desire between them burns into an all-consuming inferno, she’s scared to death that the secrets she’s keeping from him will shatter any chance they have of being together.
If Dmitry finds out the truth about her—that she might not be the good girl he thinks she is—and uncovers the lies she’s told, it may not just be a broken heart she’s left with.
Winter’s entire future could be taken from her.

Warning: This filthy, over-the-top office romance is short and sweet, with a side of spanking and insta-love. If you like your alphas possessive and bossy with a dirty mouth, then this is the book for you.
