Not sure I can come up with ten questions (don't have answers) but I can get you started.
1) How did you pick the title of your book, Artemis Fowl?
2) Who is your favorite character?
3) Did you write this book with the intention of having other books follow?
It is Sam Border if you didn't know. To know what a main character is it is the character who is talked about throughout the whole book and/or is on the cover on the book. It is a strategy to know the main character(s) of the book. I hope this helps.
