In February 2018 I released the book Tying and Fishing the ABU Optic Flies, in an English language hardcover print version. Naturally this book can be bought in our webshop, or, if you live on the British Isles, also from Paul Morgan at Coch-y-Bonddu Books.
Later last year the book was released in a Swedish language print version, by my friends at the publishing house Settern.
Now Ulla has turned the manuscript into an eBook as well, and it is available from Amazon, Kindle and ready to fly directly to your laptop, iPad, phone or Kindle reader. You find it on this link: https://amzn.to/2UgBNpa
