OK, enough mystery. My plus-sized protag is 'just fat' (option #3 in the poll). That is, it's not something she spends a lot of time gnashing her teeth about, publicly or privately.
Someone asked me why I made her so, and here's how it happened:
One of my beefs with current crime literature/film/TV is the ass-kicking dame who weighs less than a bale of hay. She can disarm a seasoned cage fighter twice her size with a single blow. Versmilitude? Pah. So, I wanted to make my protag big and strong enough that the reader doesn't blow a lobe trying to suspend their disbelief when she pops a guy in the face and he hits the floor. Then I realized that most of the women I know who meet that criteria are classified as 'fat' by people who do that sort of thing, and, having a personal interest in
the issue, I decided it was high time to write a book with a character who was 'just fat' -- a character whose size isn't shorthand for all the demeaning things that the word 'fat' has come to mean in modern culture.
When you get right down to it, though, the answer to the question of 'why?' is 'why not?' The
average adult American white chick is 5'-4" and weighs 163 pounds, but she's regularly reading books about women who are 5'-9" (or more) and 120 pounds (or less). I realize that fiction is in many ways a form of wish-fulfillment for readers, a way to vicariously engage in life experiences we'll never have in reality, but when
I read, I'm looking for experiences slightly more meaty (no pun intended) than the fantasy of fitting into smaller clothes.
Finally, here is an embarassing truth: I originally conceived of the book as a sort of 'fat'-girl revenge fantasy. My personal vicarious reading experience was starting to suffer demonstrably from the frustration of not finding books with average-sized (i.e., 'fat') characters who weren't slobs, idiots, psychologically damaged, morally depraved, derisively comical, or otherwise inferior to their uncommonly thin co-characters -- so I decided to write one myself, serving the central theme of a 'fat' (i.e., average) person winning out at the end. That lasted about a draft and a half, at which point I realized that not only was I just moving the same damned pieces around on the same damned chess board, it was boring. Julia (my protag) kept wanting to do more interesting things. So I let her, and the book turned -- thankfully -- into something else.
