Welcome to the blog, Christopher.
LOL. Give a short synop of Suicide Kings.
Absolutely. I think entire books do, let alone characters. After a bit of initial nudging and prodding, characters do begin to breathe all their own, the things they would do or not do in varying circumstances almost written by themselves. But books are organic as well. I usually start a book with a pretty good idea of where it will go, although most books will challenge that, head off in directions I never expected. It’s good to keep your options open, to let the story develop naturally.
