Vivienne "Vivi" Laurent has built her career on knowing what people want before they do. A brilliant senior brand strategist at a rival agency, she walks into Julian Mercer's world looking for the next thing worth winning. What she finds is far bigger than a new campaign, a better title, or another rung on the corporate ladder.

Julian has inherited more than a penthouse and a sprawling private estate. Hidden inside his family legacy is a formula designed to heighten fertility, reshape the body, and build the kind of family his ancestors envisioned. Vivi becomes the first woman drawn into that plan, and as attraction turns into commitment, the life she thought she wanted begins to give way to something more consuming.

Soon, the estate is no longer just Julian's inheritance. It becomes Vivi's home, her future, and the place where she carries three children who will change everything. As her pregnancy advances, Vivi must decide whether transformation means losing herself or finally discovering what her ambition was always reaching toward.

And when Julian begins looking toward the women who may come next, Vivi is no longer simply the first. She is the strategist at his side, the center of the growing household, and the woman who will help shape the future of the Breeding Executive Harem.
