Sean Leonard

Sean Leonard – Editor

Proofreader/editor for 9+ years, reader for 40+, and as a lifelong fan, horror is my go-to genre.


I have worked with Raw Dog Screaming Press, BPP, JournalStone/Trepidatio Publishing, as well as directly with individuals preparing to submit their work to a publisher. Most of my work has been in the horror/sci-fi genres, but I'm open to any genre where a good story can be told.
When you hire me to proofread your manuscript, expect the big things to be found - misspellings, grammar, the usual stuff - but I'll be checking those commas and semicolons and making sure your quotation marks are all pointed the way they should be too. If I notice a word is being used a little too often, I'll let you know. If I see potential timeline errors, character discrepancies, or just strangely worded paragraphs, I'll let you know that as well. And if you have other specific things you want me to watch for, whatever they may be, consider it done. You will see every single change/adjustment I make through the tracking tools, and I'll include notes anytime anything isn't self-explanatory. Basically, I want your final manuscript to look the best it possibly can, and I'll put in the time to make sure that it does!

I have collaborated with Sean on my debut novel and again on the second book of the series. His efficiency and knowledge of copy editing are something I can't speak enough about. I am going to use Sean on ALL books in The Glass Button Series. Thanks again, Sean! Rick

Working with Sean was a breeze. He's affordable, fast, and accurate. What more do you need? Sean will be my first stop the next time I need a proofreader.

Sean was a joy to work with. He proofed my novel and removed any awkward wording in my prose. It was just the amount of editing that I was looking for to clean things up before publishing.

Sean is the best! This is my second time collaborating with him, and it was a joy. Sean is professional, helpful and even pointed out some of my mistakes I never would've noticed. He made my book a smoother read. I can't thank Sean enough for his work. I would absolutely work with him again.
