Query: An excellent book for teens who want to lead

Holly Cefrey's, "The Art of Leadership" is and excellent book for teens interested in taking leadership roles in their school and community. Through examples and scenarios, Cefrey explains to teens how to lead by example and with confidence. I purchased this book for my teenage daughter, and it has been a valuable aid in helping her to gain confidence in public situations. Since then she has become the student body vice president, as well as the captain of the debate team.
