When her mother died two years earlier, Izzy thought the world would change in some identifiable way, but it didn't. It didn't even slow down. Along with constantly watching her brother, Jason, to ensure he didn't repeat his involvement with drugs, Izzy has managed to get through school and the rest of her life using her mother's endless rules as guidance, even making up some of her own as she goes along. When her father begins dating a woman named Anne and decides to remarry, Izzy is unprepared and convinced she will hate this intruder into her ordered life. But when Anne becomes pregnant, and her health is threatened, Izzy finds that there might just be room in her family after all.
