The book provides almost everything a girl needs to know to survive and protect herself in the digital world. It is more like a textbook. But illustrations are very good so even if it is a boring book you want to read it. There are also quizzes at the end of each section to test if you learned or just read it because your parents want you to read it. The information in the book is mostly known information but it's not a disadvantage to repeat. By the way, there are actual girl's opinions in the book. That's good to empathize with others and to feel you are not the only person who feels or thinks that way. Before giving your daughters cell phones or any personal device you should let them read this book and talk with them that digital world is both very helpful and dangerous. Good luck young lady and her parents on your digital world journey.
