According to Thomsen , she belongs to the culture of "zappers" who have grown up with computers, mobile phones and television, leading to a more limited experience of the world and fewer relationships with other people.
[1][2] Born in Humlebæk in Northeastern Zealand in Denmark, Thomsen developed her interest in storytelling while at Zahles Gymnasieskole, the high school she completed in 1989.
Thomsen then spent a couple of years studying law in Copenhagen, but then returned creating cartoons.
[2] The influence of cartoons can be seen in Thomsen's first humorous novel Af en superhelts bekendelser (Confessions of a Superhero, 1994).
Thomsen's next novel Plastic (1995) is about a girl receiving unemployment benefits who dreams of becoming a successful Barbie doll in a perfect life to come.
