I’ve just completed Blind Vertrouwen by Michael Connelly, a Harry Bosch novel in Dutch. I enjoyed and understood it. It was compelling reading (a Krashen term) since I often chose it over any English book.
It was not my first ‘home run’ book (another Krashen term). Yet it was one where I didn’t know the story beforehand—like Harry Potter. I didn’t understand 98% of the words. Perhaps I only knew 80%. However, that didn’t matter. That wasn’t necessary.
What’s next is for me to spend a solid book’s worth of time on German, then Japanese, French and so forth.
