One of the easiest ways to learn what makes a good, standard query letter is simply to see an example of one that does its job well. If you write fiction or narrative nonfiction, a query letter is your first (and often, your only) chance to get an agent interested in reading (and, with hope, signing) your work. You should put just as much care and attention into crafting and polishing your query as you did into your manuscript. After all, if your pitch doesn’t hit its mark, your book will never leave your desktop.
The main objective of a query is simple: Make the agent care enough about your protagonist and your plot that she wants to read more.
