On marketing: release a fragment of the book on WriteOn. (this one is from Dar)
I like it. Which portion is debatable. While the prologue is, basically, a self-contained short (well, a 14,000 words short) story, it is seemingly unrelated to the events of the book, yet it is a clear character introduction, and the world-building is rather different from what I read before.
Another idea: release a free chapter in an audiobook form (guess, who would be asked to narrate :-)…)
I am thinking The Orange Tent, for it is a single female POV, and that chapter is directly related to the story, and has a small-scale, but quite inciting event for my main female character.
The tally of words as of today: 325,566 out of (tentatively) 400,000. I like round even numbers.
