Ellen's relationship to Andy doesn't just seem perfect on the surface, it really is perfect. She loves his family, and everything about him, including that he brings out the best in her. That is, until Ellen unexpectedly runs into Leo. The one who got away. The one who brought out the worst in her. The one she can't forget. This is the story about why we chose to love the ones we love, and why we just can't forget the ones who aren't right for us. Emily Giffin brings both humor and heart to her novels and has an uncanny ability to tap into the things women are really thinking and feeling. With LOVE THE ONE YOU'RE WITH, she proves, once again, why she is the fastest rising star of women's fiction writing today.
