Sean Leonard - Editor

Hanson, KY, USA

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!
