Love and Hate: a novel of bloodlines

Two sisters, separated at birth, having grown up in different families unbeknownst to the other, come to settle in the same city and eventually date the same man. Discouraged by the adoption agency that pointed her to the wrong biological mother, the elder sister pursues a television career that engulfs her life; while the younger sister, beset by depression and unsteady liaisons, channels her sense of emptiness into a hit young adult book.
