Somewhere Sisters by Erika Hayasaki is the true story of identical twin sisters separated shortly after birth. One is raised by her aunt in Vietnam while the other is adopted by an American family along with another girl from the same orphanage.
The author provides historical and scientific background about adoption and twin studies throughout the book. The twins, Isabella and Ha, don’t learn about each other until they are quite a bit older. The book switches back and forth between each sister’s different upbringing and reaction to finding out about the other. While their experiences are very different, both are raised with lots of love and an appreciation of learning.
Eventually the girls meet. It takes time for them to build a relationship, but their bond becomes very strong. This is an interesting read about family, history and values.
