I loved Brief aan de Koning when I was a kid, but I never got around to reading the sequel. When her books were republished three years ago, I first had to have the one I remembered and then started collecting her scifi novels, a treat to read (and it's true what they say that stories about the future tell you more about the time they were written in than about what's going to happen; it's endearing how she envisioned communication in space back in 1969)
Now I finally got a hold of Geheimen van het Wilde Woud I want to reread Brief aan de Koning first:)
