Found several difficulties in translating the first book. It's my first, anyway. (Translating a book, that is. I've done translations for documents and all in the past.) For the second book, I had fun! I enjoyed the story even though finding the right/suitable translation for Carnivorous Carnival can be mind-boggling.
Whenever I'm down or feeling like giving up, I leaf through the pages and get the spirit once more to keep on working.
Now, four more books to translate!
