I have chosen an author name (English that is). After careful consideration (tossing a coin) I chose the name Kay Shapiro.
Regarding publishing, I halted my collaboration with the publishing firm that contacted me earlier. I did some research and it didn't take long to find some rather bad reviews for this publishing company. After reading through a detailed description of a Finnish author's experience with the company, I ended my communications with them.
Currently I am waiting for a reply from a professional editor that I have been in contact with. I'm hoping it will help me get a footing in the publishing world. In the meantime I have started writing my first Icelandic novel. This will be the first full novel I'll write in my native language. The story is a thriller and it came to me almost complete (and in Icelandic). Now it's just a matter of getting it down on paper :-)
