Early in my publishing career, someone told me I'd need to have five books in print before I could quit my job as a journalist. Turns out it was closer to 10 books. It also turns out that while it's great to see my titles on bookstore shelves, my best customers are schools and libraries.

Among my books, the ones that sell best are for readers between the ages of 8 and 12. According to a study by the Association of American Publishers, the largest area of industry growth in 2014 was in the children and young adult category.

We live in a crazily youth-orientated world nowadays. It's a trickle-down thing. We see pictures of lithe, attractive celebrity couples such as Brad and Angelina or the Beckhams cavorting around, covered in tattoos, stomachs as flat as the singing in early 'X Factor' rounds.
