I asked queenoftheskies today how she went about building a scene list, but if anyone else would like to share their process in the comments, I'd like to hear it.
I still haven't gotten to the bottom of the oh-so-difficult, "What is this story about?" question because I'm one of those writers who has a vague idea but knows something deeper will come out in the writing. In other words, I won't know what I'm trying to say until I say it. On a positive note, though, blabbing to mana_trinireally helped me find the focus in the third storyline, which gave me an additional angle to use to bring the three plots together and give them resonance.
However, something tells me it won't be as easy as all that given the book's structure; a large part of it will be letters, diary entries, translations from ancient tablets, journal clippings. Anyone have any recs for good epistolary works? (Not too worried about genre at this point)
