Noun
query letter (plural query letters)
A formal letter sent to an editor, literary agent or publisher in order to propose an idea for a written work.
Above all, a query letter is a sales pitch and it is the single most important page an unpublished writer will ever write. It's the first impression and will either open the door or close it. It's that important, so don't mess it up. Mine took 17 drafts and two weeks to write. Nicholas Sparks
I wrote a query letter to an editor - a friend of a friend. The editor called me an idiot, told me never to contact an editor directly, and then recommended three literary agents he had worked with before. Laurie Fox was one of them, and I've never looked back. Daniel H. Wilson
