Which made me wonder: how many of us have a list of pen names we would use in this situation? I know I do. I skip the most obvious one, which is my actual legal name (Marissa Gritter), because I have a possibly weird personal bias about pen names, and this bias only applies to me: I am not Dutch. I don't want to use a Dutch name for my writing because I am not Dutch, not Dutch-American or Dutch-Michigander or any other thing that might tie to being Dutch. I am greatly fond of my Dutch-Michigander husband and in-laws and those of their Dutch-Michigander friends and associates I have met, but if it is true as they say in Grand Rapids that if y'ain't Dutch, y'ain't much, I am, in fact, not much. But I would write as a Fossback, because that was my Gran's name, or as a Haugan, because it would amuse me to go incognito as Ms. Norwegian Underhill, or as a few other things that are both ethnically appropriate to me and reasonably spellable.
(As I said, this does not apply to you lot. If you are Italian-American and you write as Julio Nguyen-Markowicz, I would not be the least put off by that. But the only exception for me personally that we've joked about is that if I start writing teen romance novels, I would do so as Melissa Glitter. The likelihood of this is well into the negative numbers--I can imagine writing in a lot of genres and categories, but none of them are romance.)
So. Do you know who you'd be to fool bookstore computers? And do you have a rationale? ("I like that name" is a rationale.)
