Cora Whitlock has built her life around control. Sharp, disciplined, and quietly ambitious, the twenty-six-year-old media buyer knows how to read a room, manage a campaign, and keep her private desires carefully contained.

Then Julian Mercer asks her to dinner.

What begins in his city penthouse soon leads Cora to a secluded estate, a mysterious family supplement, and a future unlike anything she ever imagined. Vivienne Laurent has already chosen that life, and seeing what Vivi has built forces Cora to confront what she truly wants. As the supplement changes her body and the estate begins to feel like home, Cora makes a choice that will bind her to Julian, Vivi, and the growing family around them.

Her pregnancy with triplets transforms more than her body. Cora chooses a home of her own, discovers an unexpected bond with Vivi, and begins helping shape what the estate will become. But even as she prepares for motherhood, the future refuses to wait. Vivi is ready to begin again, new candidates are emerging, and the next woman may already be standing at the edge of Julian's world.

Cora came to the estate as the second. By the time her story is finished, she understands that she will not be the last.
