Collaboration request! Joop ter Heul, the book that inspired Anne Frank's diary

Hi guys, during Covid I found a post on this forum calling for a translation of Joop ter Heul’s school days. Most of the debate was taken up by copy right issues, sadly, but the copy right has now expired and I have made a translation of Joop ter Heul’s Schooldays. It was the book that inspired Anne Frank to write her diary. The book was written in 1919 by Cissy van Marxveldt and inspired many generations of Dutch women, including Anne Frank, but also Queen Juliana, to start similar diaries, pretending to write to a friend. I am looking for readers/collaborators and then I want to put it in the public domain. Perhaps project Gutenberg? Any advice would be welcome.

What do you want the collaborator to do?

I’d like someone to read it and perhaps make suggestions. I am Dutch and I know the books, the entire series. So a second opinion would be great.
