PROOFREADING: I will read through your book, correct typos, spelling, punctuation and word usage errors. I will do it, but I prefer NOT to do straight proofreads, because it's too hard to see a mistake and think "that's not my job, I am proofing - not editing!" and then just leave it there.
COPYEDITING: I will edit for sentence structure, story consistency, grammar/syntax, and basic interior formatting, and also proofread.
EDITING: I will review/edit text for substantive edits, content, continuity, and cohesiveness, polishing your book to as near perfection as we can get it. I will discuss with you storylines that need closing, threads that are left hanging, plot points that need clarification, etc.
Whatever changes I do make, I take pains to keep YOUR voice, and not insert my own. Any changes to a character's dialogue will be made in the character's voice/speaking style. I will not ever make any major changes without discussing with you first, and will never change events or storylines.
