A great idea isn’t enough to get something published.
There has to be an interesting situation (or, better yet, lots of them). There has to be a cast of characters that are relatable or intriguing (or, better yet, both). Your words have to make a reader gasp, or giggle, or reflect, or cry.
Most importantly, your writing has to have heart.
When an aspiring author submits a manuscript, it’s nice if they know the mechanics of a book–a narrative arc, character development. To be honest, without those, a publisher (or a reader) most likely wouldn’t give that writing a second look.
But there are things an author can revise. They can develop further a character, or be more precise about word choice. They can look to make the book better mechanically. A publishing team makes a wonderful partner in that process.
So, before you submit your manuscript, please make sure it’s been proofread and revised so it’s the most interesting, best book it can be.
Oh, and make sure it offers a great idea.
But you better make sure it has heart.
