I have finally been able to release Anuanna on Amazon in paperback! But, because the novel was too big, I had to split it into parts, so it's now Anuanna part 1 and part 2. They can be found on Amazon by simply searching Anuanna or Anuanna: The Karda Jewel.
Anuanna is also still available as an e-book which can also be found on Amazon.
To all those who have read it and sent in your advice and views, I thank you very much for the help and also for your kind words! I hope you really enjoyed reading!
