A good read for girls 8-12

I was doing a little morning reading today and came across an article in USAToday. I remember thinking this book was well-written and respectful when it first came out.  I thought I would pass along this recommendation. It is a friendly, age-appropriate book intended for girls ages 8-12 to use as a resource as they go through the "tween" years. The original book has been revised and there is a new, more detailed book that "covers new territory, in terms of brain development and moods, social interaction…". Although this is not exactly in my age niche, I always like to share info. 🙂
