Query: A very good book

Candice Delong wrote a great book, but more than that she is a great person. I enjoyed everything I read, her style was entertaining, and her accounts of her life in the FBI were thrilling. She made the FBI seem real and amazing. I would love to follow in her foot steps, become a FBI Agent and write a book that is as good as this one!P.S. Candice, I just want to say that your book is an inspiration to me. It would be my honour if you would email me someday.
