Katherine has spent her entire life striving for perfection, and her hard work has finally paid off. After seven difficult years of trying (and failing) to conceive, Katherine gives birth to Rose, her IVF miracle child. But one thing isn't quite perfect. Rose's pale skin doesn't match Katherine's complexion, and an irritating doubt begins to grow in Katherine's mind. Tess underwent IVF at the same clinic as Katherine, but after finally conceiving, Tess' daughter was stillborn. Now, nearly one year later, she's approaching rock bottom. But shortly before Rose's first birthday, Katherine and Tess get a call from the fertility clinic: Their eggs were switched. As Katherine's carefully planned life begins to crumble around her, Tess finally sees the glimmer of hope she needed to get her life back on track.
