Red pen, don't fail me now

I'm about halfway through the second pass of my sister-in-law's novel, and I'm hoping to have it done and e-mailed back to her by the end of the week. Then I'll finally have time to get back to my own novel. I love editing--Developmental English was my favorite class to teach--but I love writing too, and sometimes (as I've blathered on about before) there just aren't enough hours in the day to do both.
