I am a grown woman with two much younger sisters and this book is great! I only wish that they would publish it in American English as well. It was concise, easy to understand with small blurbs from other girls, and it didn’t overwhelm in the information that it gave. Honestly, I wish that I had this book when I was prepubescent because coming from a very religious household, many things weren’t told (or fully explained) to me like this book does. I often felt wrong or dirty for the things that I didn’t understand and I see the huge disservice done to me as a means of religious control. I’m gifting it to my little sisters and letting them know that I will always be around to talk and answer questions. When I gift it, though I’m going to give them a little list of translations for British English to American English so that they don’t get caught up on words like “loo,” “knickers,”, “rows,” etc.
