Ask your friends. Ask your parents. Ask someone you hardly know. The Book of Questions gives you permission to ask those things that are too bold, too embarrassing, or just too difficult to ask by yourself. You will find questions of integrity; of sex; of what you would do for money; even things too personal to talk about out loud.

Whether you use it as a tool for self discovery, or as a provocative way to stimulate conversation, this book constantly challenges attitudes, morals, beliefs-and it challenges you.
