Finding the best way to query your work is a good start. Read everything you can about how to write a query that will get a publishers attention.
It’s the hardest part because you have worked long and hard to get your work to the best it can be.
Selling it to someone is a scary thing…it involves rejection and that is so hard to take.
Putting your baby out to auction is why many writers don’t go thru the query process.
You have to find the best way to support what you have written and then let it go.
If you find rejection comes your way then try posting your query on CC and see what others have to say to help.
