"Late one evening in June 2009, with nothing but time on my hands, I posted a simple question on my poetry blog, Lyhyttavaraliike. In effect, this is what I asked: Who wants to author my next book?"
This is how Karri Kokko writes in his Foreword to this book.
Yes, you can be out of ideas, but no matter -- maybe somebody else will pitch in and write your next book for you.
As Kokko says, "I sure enough didn't have to wait long to get an answer".
