A strong book proposal is critical to the marketability of a manuscript. Literary agents and publishers need to see concise, engaging text that keeps manuscripts off the slush pile.

We’ve written many book proposals. Experience has taught us what literary agents and publishers are looking for, and we know how to pique their interest in a book.

Writers have only one chance to make a good first impression with top-tier literary agents and publishers. Don’t squander that chance by sending them an anemic or misleading book proposal. We can help you avoid making that mistake.

Let us craft a strong book proposal from your completed manuscript, and we’ll give you the names and addresses of the right literary agents for your book. We’ll also be there to lend a helping hand if you encounter a problem or need advice during the querying process.  

The anatomy of an Open Book Editors book proposal

A typical book proposal consists of four elements:

  • a one-page query letter
  • a two- to four-page synopsis of the book
  • a chapter-by-chapter outline
  • a one-page author’s bio

These are the elements you’ll need when querying literary agents and commercial publishers. Most require that you submit the query letter and brief synopsis first. If they like what they see, they’ll ask for a more detailed chapter-by-chapter outline of the book, and either sample chapters or the entire manuscript.
