After you’ve created a list of which YA agents you’d like to submit your manuscript to there are a few things an agent will request before he/she requests your entire manuscript. The query letter is one and the synopsis of your book is the other. The synopsis basically plots out your story along with your Protagonist’s emotional journey. It doesn’t have to retell ever detail but it should retell the story from beginning, middle, and end.
There are two great articles about writing a synopsis. Just check out the links below. The tough part( writing the book) is over and now it’s time for you to reap the benefits of all your hard work.
