I then came home and began proofing - I did about twenty-six pages' worth of actually reading the book, but after that I just went page to page looking specifically for bad breaks, em dashes, and that kind of thing. That took about three hours and I found about thirty things, noted them in red and then began looking through again. I caught a couple of formatting things that Grant hadn't fixed, but mostly it was em dash, bad breaks, and spacing issues. The least amount of fixes we've ever had.
