The Donovan Dynasty Series

His erotic demands test everything she believes.

When the fearless, larger-than-life Nathan Donovan becomes her boss, Kayla Fisher’s life is turned upside down. The multimillionaire wants her by his side, but his demands don’t end there.

The youngest, boldest of the dynamic Donovan brothers, Nathan is accustomed to getting what he wants. And he focuses his attention on the smart, sexy Kayla Lane. He quickly discovers she’s unlike any woman he’s ever known.

She meets him, desire for desire, getting deep inside him, destroying the barriers he keeps around his heart. He wonders, though, if she’s willing to give him the one thing he demands…

“This third book in the linked novels of the Donovan brothers delivers brilliantly. There is nothing false about Nathan Donovan’s Dominance or his personality. They mesh in a very satisfying manner that will ring true with anyone who recognizes that great Dominants are neither arrogant nor boorish; rather, they are confident, intentional, focused, and success-oriented. Nathan Donovan is is all of these things, and more, as the exceptionally successful and exceptionally young CEO of Donovan Logistics. He knows what he wants in business, and he knows how to get it with aplomb. He has no idea what he really wants in a woman.

But that woman is Kelsey Lane, who is no shrinking violet submissive. In fact, she is almost entirely unexposed to the world of Dominance and submission until she meets Nathan Donovan and his precision-guided intent to acquire the business for which she is effectively the chief operating officer, although neither her title nor her compensation is commensurate with her skill. Very shortly after meeting, Kelsey finds herself the recipient of not only Nathan’s admiration and consternation because of her deft handling of several conflicts, but of his dominance because he wants her. He wants her like he’s wanted no woman before, and it grows in intensity and power as they spend increasing amounts of time together at work and outside the office. The sex between them is hot, and gets hotter the more Kelsey leans into her submission and the revelation that it frees her to own her body image, her sexuality, and her confidence. She knows how valuable she is, and she knows what she wants, but she comes to believe it in a deeply empowering way as she pursues her relationship with Nathan, and as she decides to end it. The resolution of that interpersonal conflict is satisfyingly weep-worthy, and wonderfully fulfilling. It is so well done that I will not provide spoilers for the unfolding of the conclusion.

No review of this novel could possibly be complete without mentioning Nathan’s wristwatch from Julien Bonds. That watch is a Dominant unto itself and very probably deserves its own book. It makes every other smartwatch seem like a portable sundial. I wish I had thought of it. And to anyone intimately familiar with the world of D/s, it provides a satisfying and highly entertaining mini-antagonist for Nathan.”
