Copyedit fog

Finished the latest copyediting round for my next book,Very Mercenary. The way it works is this: I get a package (FedEX) with the manuscript (ms, not bound) and an editorial note. Depending on when I've submitted the manuscript and how long it's taken to do the bulk of the "major" editing, I have a few days to a week to turn the copyedited ms around. Not much. Many sleepless nights. The copyedits range from typos and minor grammar changes to plot holes (Weren't his ears missing?). Went well this time but many beers are needed for a full recovery.
