A query letter is like the first phase of a job application. You want to make a good impression so that the agent or editor will give you an opportunity to submit your proposal — the equivalent of a first interview in a job hunt. Normally, there are certain questions every agent and editor expects will be answered in your query letter:

• What is the subject and slant for your book?

• Why is your book needed?

• Who will read your book?

• How are you qualified to write the book?

• How enthusiastic are you about your book?

• How professional is your presentation?

Also, a query letter must include your name, address, telephone number, and e-mail address (if applicable). And if you'd like a response, be sure to include a self-addressed stamped envelope, labeled with your name and address.
