Here is his bio from his website:
“Brandon Mull is the author of the New York Times, USA Today, and Wall Street Journal bestselling Beyonders and Fablehaven series. Brandon resides in a happy little valley near the mouth of a canyon with his wife and four children. He spent two years living in the Atacama Desert of Northern Chile where he learned Spanish and juggling. He once won a pudding eating contest in the park behind his grandma’s house, earning a gold medal.”
1. What helps you to keep writing?
Good scenes keep me writing. Make every scene count. Make sure every scene engages you (because it is funny, or revealing, or amazing, or tense, or whatever). Pay attention to how your favorite writers build their scenes--how they start, how they handle dialog, how they work in backstory, how they paint on your imagination with descriptions, how they end the scene, and what they skip dramatising in a scene. If you write good scenes, then string them together in a smart way so that as a whole they convey a complete story, your readers will have a good time.
2. Do you ever come to your writing with a problem you are dealing with in your life and then try to write through it?
3. How did you start up the Spirit Animals series?
Scholastic came to me with the premise, but I served as architect for the series, creating the characters, the world, and outlining all seven books. I then wrote book one. There will also be a bonus book of stories about the Great Beasts, and I wrote one of those stories.
4. What other books do you have coming out soon?
(With the Candy Shop War) there will probably be a third and probably final novel called The Carnival Quest, but it is four or five years away due to contracts for other books.
Scholastic released, like 39 Clues, Spirit Animals, written by a team of authors. I wrote book one and the outline for the other six books. See more here http://oomscholasticblog.com/2013/03/spirit-animals-cover-reveal.html
Then I have the series called Five Kingdoms, a five book series where our main character crosses over to another world, but with a lighter feel than Beyonders. It'll be true middle-grade like Fablehaven, but the world where he goes will be really different from anything we've seen. The first three books will come out only six months apart from each other.
And then in 2015 there will be a sequel series to Fablehaven called Dragonwatch. It will be five books and will continue the main storyline of Fablehaven, following Kendra, Seth, and the other main characters.
