They run something of an audiobook industry at home in the villa in Häljarp - she in the basement in front of her laptop, he on the sofa in the living room.
Together they write twelve books a year - completely adapted to the audiobook consumer.
- It's going really well right now.
This year I have been able to stop writing ghosts for others, says Leffe Grimwalker.
In the clip above, the couple talks about what is required of authors who write for the audiobook market.
Can soon live on writing
They met almost ten years ago.
Some distance into the relationship, the couple formulated a goal.
Within five years, they could live on their own writing.
- Now we are almost at the finish line after eight years.
Leffe is there, but I still have my part-time job at the university where I teach creative writing, says Caroline Grimwalker.
2020 meant a shift in the book industry.
For the first time, digital books about the printed books went in the number of copies sold.
- Now the entire publishing industry has followed the trend and must adapt the book to this format, says Leffe.
Caroline believes that the audiobook and the printed book fulfill different but important functions.
- It is good for the audiobook if there is a paper book and vice versa.
My feminist trilogy The Breakwaters was written exclusively for sound.
But it was such a success that it now also comes on paper.
Still outside the fine room
Caroline Grimwalker is soon up to date with a new suspense series about a woman who infiltrates the Swedish far right.
Leffe Grimwalker has recently released the fifth part of the series about Alex Storm, a family man who is drawn into the criminal life in Hong Kong.
Are you admitted to the literary fine room now?
- No, I have never been because I wrote an autobiographical confession novel and then a lot of horror.
So I have always crawled to the bottom of the ugly and enjoyed it there, says Caroline.
