Bestselling author Colleen Hoover's new novel about an unhappy marriage and the one long-forgotten promise that could save it. Quinn would never have thought that she would meet the love of her life on the worst day of her life. But that's exactly what happens. The beginning of her relationship with Graham is absolutely perfect, they are like creatures for each other. But seven years later, their marriage is in ruins. The initially perfect love is threatened by a thousand imperfections in their life together. One would say that a marriage stops working when love is replaced by malice and contempt. But Quinn and Graham aren't mad at each other. They're just not the same anymore... All the shared dreams and memories, instead of holding them together, separate them. And the only thing that could save them will most likely destroy their relationship irretrievably...
