I was born in Denmark on a dark and stormy night in November 1976.

I began writing as a teenager. My first book was a really awful horror novel titled Nidhug’s Slaves.

During the next 6 or 7 years, Iwrote nearly 20 novels—all of which were rejected—while earning mydegree in education and becoming a part-time teacher. The rest of the time I spent writing.

In 2000, after seven years of hard work, my efforts finally bore fruit and I debuted with the fantasy trilogy The Battle of Caïssa.

In the spring of 2007 I became a full-time writer. Since 2000 I have published over thirty books for children and young adults in genres ranging from fantasy to horror and science fiction.

My books have been published in more than 15 contries. From 2013-2015, my series about the superhero Antboy was made into three films, and they became an international success. Currently an animeted tv-show is under development.

In 2018 The Devil's Apprentice will come to life on stage in a musical version.

Brief facts about me:

· I live in Copenhagen with my wife, two kids, and a dog.

· I'm a big fan of Stephen King, Bruce Lee, and the Dave Matthews Band.

· I've taken lessons in karate, judo, jiu-jitsu, taekwondo, and ninjutsu, but have never advanced beyond white belt.

· I'm allergic to cats, pollen, and people who snore.

· I've travelled to Australia, Africa, USA, Hell, the future, spent a night with Death, possessed super powers, and witnessed the demise of Santa Claus.
