On their seventh anniversary, Linda Calloway finds out her billionaire husband Everett cheated. She doesn’t leave. She opens the leather vow book they wrote on their honeymoon, with fifty promises each, and puts him on probation: one promise a week, with a Sunday Review where she rules Kept, Broken or Renegotiated. If he breaks one more, she signs the divorce papers in her purse. Her own promises are on the facing page, and she breaks several.

He gave me a ring and promised me forever. I never knew forever had once belonged to another woman. On our anniversary, my husband sent me a message that made me smile like the woman who had fallen hopelessly in love with him. Grant Mercer was everything a woman could dream of wealthy, powerful, devastatingly handsome, and heir to a luxury hotel empire. To the world, he was the perfect husband. To me, he was the man who had once made me believe that love could be a beautiful, lasting thing. I thought I knew every part of him. I was wrong. It began with a jeweler's receipt I was never supposed to find. One name on that tiny piece of paper threatened to unravel everything I believed about my marriage. Sloane Avery. His former fiancée. The woman he swore belonged to his past. Desperate for an explanation, I went looking for my husband. Instead, I found him kissing her. On our anniversary. When Grant turned and saw me standing in the doorway, he said my name as though that alone could undo what I had witnessed. He called the kiss a mistake. He insisted the past meant nothing. And when I discovered that the diamond ring on my finger had originally been chosen for the woman before me, he expected me to believe that giving it to me had somehow made its history disappear. But how do you trust a man who can look you in the eyes, promise you forever, and keep another woman's place in his heart a secret? How do you compete with a ghost from his past when that ghost knows promises your husband has never told you about? I am Lila Hart Mercer. I married into one of New York's most powerful families, and somewhere along the way, I began to lose pieces of myself trying to be the perfect wife. I put my dreams on hold, made excuses for the silences, and convinced myself that the man I loved would always choose me. Not anymore. I will no longer smile for cameras while my marriage crumbles behind closed doors. I will no longer accept expensive gifts in place of honest answers. And I will not spend the rest of my life fighting to be first in the heart of a man who made me his wife. So I make new rules. No pretending. No more half-truths. And no forgiveness simply because my husband still knows how to make my heart race. Then an opportunity to reclaim my abandoned career brings me back into the world of luxury design and directly into the path of the man I am trying to forget. As my independence grows, so does the distance between the woman Grant married and the woman I am becoming. The chemistry is still there. The memories still hurt. And despite everything he has done, a single look from Grant can awaken feelings I wish I could bury. But attraction is not trust. And love is not an excuse. Meanwhile, Sloane is not finished with the future she believes Grant promised her. The deeper I dig, the more I discover that the kiss was only the beginning. There are old promises, unanswered questions, and secrets surrounding the very week Grant and I were supposed to begin our forever. And then there is Ethan Cole, a man who sees my talent, respects my boundaries, and offers me something I had almost forgotten I deserved: the freedom to choose without being controlled. For the first time, I must ask myself a question that terrifies me more than losing Grant. Am I fighting for the man I love or for the life I sacrificed to build with him? Grant says he loves me. He says he made a terrible mistake. He says he wants his wife back. But apologies are easy for a man accustomed to getting what he wants. If he truly wants me, he will have to face the truth he spent years avoiding, accept the consequences of his choices, and learn that he cannot buy his way back into a heart he has broken. Because I am no longer the woman who will accept whatever pieces of his love he chooses to give me. And the ring? It no longer represents a promise he made. It represents a choice I have yet to make. He once gave me a ring that was meant for another woman. Now he must prove that the love he offers me is finally, completely, and honestly mine. But when the truth about our past finally comes to light, will love be enough to save our marriage or will the secrets he kept destroy the last chance we have to begin again? Some promises are broken with a kiss. Others are broken by everything that comes after. Welcome to a story of forbidden memories, dangerous secrets, undeniable chemistry, shattered trust, and a woman who must decide whether the man who broke her heart deserves the chance to win it again.
