A synopsis is a summary (usually 1 page single spaced) of your entire manuscript. For many writers, it’s the hardest piece of a query package to write.
- Jane Friedman’s blog offers an excellent post on writing a novel synopsis. https://janefriedman.com/how-to-write-a-novel-synopsis/
- Susan Dennard’s guide to writing a synopsis is the go-to resource. https://stdennard.substack.com/p/how-to-write-a-1-page-synopsis
There aren’t as many resources on synopsis writing as on query letters, but you likely don’t need any beyond these two.
