Query: A must have

I love this book and not just because it's filled with pictures of georgous celebrities, but the author Kevyn is a genius! He makes the exotic and runway looks so accessible to everyone. Some good brushes, a perfectly matched foundation and your face becomes a palette. I've been into makeup so long and this is the first book I've been able to put my hands on that spells out the techniques. All my girlfriends have borrowed it already and we look more fabulous than ever!
