Sierra March

She built his empire. Then she walked away. For years, Margaret Wren was the invisible force behind tech billionaire Nathan Cross. She managed the chaos, fixed the disasters, and turned impossible demands into seamless success-all while he took the credit. To the outside world, Nathan was a genius. Behind the scenes, it was always Margaret. Until her body gave out before her spirit did. A hospital stay becomes a breaking point, and for the first time in years, Margaret chooses herself.
She walks away from the empire she built for Nathan-straight into an uncertain future. And into Gerard Holt. A rival billionaire with sharp instincts and an even sharper eye for talent, Gerard has been watching Margaret for years. He doesn't just see what she does-he sees what she's worth. His offer is simple: a partnership in a new venture where Margaret isn't the power behind the throne. She is the throne.
Together, they launch Holt & Wren, a consultancy that moves fast, wins big, and turns heads across the corporate world. Success comes quickly-almost too quickly-and with it comes attention, pressure, and the return of a man who refuses to let go of what he believes is his. Because Nathan isn't done with her. And when ambition turns desperate, the stakes become far more than professional. As lines blur between partnership and something far more dangerous, Margaret faces the one risk she's never allowed herself to take: trusting someone who wants all of her power-and all of her.
A sharp, sexy, and deeply satisfying story of reclaiming your voice, owning your brilliance, and choosing love on your own terms.
