I often come across submission guidelines that request that an author's query say "why you are suited to write this particular book." I understand what that means in the context of nonfiction, but I am having trouble understanding what it means in the context of fiction. What does it mean to be suited to write a story you have utterly made up? I am suited to write this science-fiction novel because I once went to the Air & Space museum? I am suited to write this romance novel because I like boys? Obviously this is not what is meant here...but I'm having trouble thinking why I'd be particularly suited to write the book I have written, above and beyond any other decent writer.
