I follow her on Tumblr and as of April of this year she was still working on it, but it will be a slow process. Here is what she replied to an ask:
"Hi, I am not well. My laptop broke so I have lost everything on it, including my 5-years-long word document about OLYMPUS and all my other wips. I have worked on my iPad on days I have energy. But these days are rare and it is hard to come back to Tumblr and see a remainder of my failings and the 850 people waiting on me.
Sorry to disappoint. I wish things were different.
I will continue working on Olympus. I will finish this story, i love it too much let it die. I just hope you’ll still be here then.
Love, Elena"
