In a 2008 interview, when asked "we understand that writing the "Bird" series has not been finished. Please let us know your future writing plans," Lee answered laughing: "there are lots of rumors[...] About this 'Bird' series too. I never declared that I would write a series, but before I knew it, the new quartet or new saga has become the ambition of this typer's life. Well. If a story that I want to type comes up I will type it, if not I won't type it. I don't have any ambitious plan going 'I will type before I die!'"
