So you have your hook, your synopsis, and now you need your bio. List any published works that relate. If you’ve published a short story, super awesome. If you won a school poetry contest in fifth grade, not so much.
If you don’t have any writing credits, don’t write anything. An agent does not need to know your marital status unless your book is on a healthy marriage or living single. You don’t have to say where you’re from unless it’s relevant. Believe me; it’s better to write nothing than bog your query down with useless info.
If you don’t have a relevant bio, just thank the agent for their time. Make sure you reiterate the name of your book and the word count. Keep it professional. My ending was simple.
In the After is completed at 96,000 words. I would be happy to supply sample chapters upon request. Thank you for your time.
Just remember; agents want to know the title of your book, the word count, and the genre. Make sure you have these three things somewhere in your query.
