Aria Knight is turning five. And instead of toys, cakes, or ponies, she wants just one birthday gift: a mummy. Alexander Knight—ruthless billionaire, single father, and man who has everything—suddenly realizes there’s one thing his wealth can’t buy: love for his daughter. When his little girl insists, he makes a promise he doesn’t know how to keep. Then comes Emilia Hayes—Aria’s gentle schoolteacher with a kind smile and a past she keeps carefully hidden. She’s everything Alexander’s icy, calculated world isn’t. His daughter adores her. He finds himself watching her. And when circumstances force him to make a deal… Emilia becomes part of a bargain that changes everything. But in Alexander Knight’s world, nothing comes without a cost. Enemies lurk in the shadows. Secrets refuse to stay buried. And what begins as a bargain might turn into the one thing neither of them expected—a dangerous, undeniable love.
