And it turns out she does! While beauty is a huge interest for me, I still found plenty of tips in the book that I found useful, and Zoe has a really cute way of writing too, since she mixes some short jokes with actual tips, and the book covers everything from skin, make up, eyes, complete looks and much more, so if you want to improve your knowledge on everything related to beauty, you can really get started pretty well just by getting this one book.
Oh and by the way, this is a book to fit all ages, since she gives tips based on your age too. So no matter if you are young or a bit more mature, you'll probably find this book useful! Highly recommended!
