Every child's taste is different. Don't worry if they're not reading 'War and Peace' at age 12. First, build a good foundation and a positive attitude about reading by letting them pick the stories they enjoy. Make friends with a bookseller or librarian. They are a wealth of information on finding books that kids enjoy.

I don't think about being famous, really. Being an author, I don't generally get stopped as I walk down the street. It's not like being a movie star.

I've always liked the idea that writing is a form of travel. And I started my writing career as a mystery novelist for adults.

When I write, I'm still imagining a kid reading it on paper. I read e-books when I travel, but in general I still prefer holding an old-fashioned book in my hands. There's a special, tactile experience.

I've been reading Greek mythology since I was a kid. I also taught it when I was a sixth grade teacher, so I knew a lot of mythological monsters already. Sometimes I still use books and Web sites to research, though. Every time I research Greek mythology, I learn something new!

I'm a teacher still, but with a much larger classroom.

As a teacher, I've never seen anything like 'Harry Potter.' That's why I smart when people talk about the 'next' 'Harry Potter.' There is no 'next' 'Harry Potter.'

I tend to think of a myth and then explore how it would play out if it were happening in the modern-day world. I modify all the myths I use, but I stick very closely to their structure - it is the hidden teacher in me.

I loved the idea of making history interesting for kids! When Scholastic approached me about 'The 39 Clues', I immediately started going through the 'greatest hits' from my years as a social studies teacher, and picked the historical characters and eras that most appealed to my students.

My goal in the classroom was always to make sure they were having so much fun that they didn't realize they were learning.

I have a great deal of sympathy for reluctant readers because I was one. I would do anything to avoid reading. In my case, it wasn't until I was 13 and discovered the 'Lord of the Rings' that I learned to love reading.

I think kids want the same thing from a book that adults want - a fast-paced story, characters worth caring about, humor, surprises, and mystery. A good book always keeps you asking questions, and makes you keep turning pages so you can find out the answers.

When I was young, my favorite picture book was 'Fletcher and Zenobia,' written by Edward Gorey and illustrated by Victoria Chess. It's long out of print now, but its mix of macabre humor and 1960s psychedelia made it a perfect children's book for the times.

I do like to wrap things up and leave some things to the readers' imagination.
