" I enjoyed this book, but I think might have been better as a long article than as a shortish book. It seemed kind of padded out with stories of other twins and summaries of different nature/nurture studies, which were somewhat interesting, but not really necessary. I like the way the story is told, alternating between the twins' voices, and I really admire their honesty about their feelings. Paula, in particular, was brave to express her anger at having this life-changing news just blurted out to her over the phone, out of the blue, and her fears of her sister expecting too much and taking over her life. Really the best thing about this book, though, is that I learned about Poto and Cabengo (Grace and Virginia Kennedy), American identical twins (born the same year that I was) who spoke to each other in their own invented language. I LOVE learning about stuff like that. "
