I'm almost ready to submit my 102,400 word fantasy novel TRAITOR KNIGHT to an agent. The submission guidelines say 'submit the first ten pages with your query'. My first chapter is six pages; the first two chapters together total sixteen pages.  So my question is-- do I submit only: a) the first chapter (six pages); b) the first ten pages, which rather breaks in the middle of a scene); or c) the first two chapters (all sixteen pages).  Opinions? I'd love to hear recommendations on this.
