I can recommend Jane Lindskold's fantasy Through Wolf's Eyes. I made only a short break for dinner and read far past midnight. And I wouldn't have put it down if I didn't need some sleep to get through a day's worktime.
Today, the internet access of our local office went down in the morning (or maybe already in the night, I don't know) and didn't get up again. Estimates said tomorrow and in the afternoon I recherched at home for prices we needed asap.
Since I could only work at it later I spent my time with various administrativa. One of them was estimating my hours at the office. We have to record them from now. I discovered that the days when I go to the gym and leave a bit earlier is cutting into the time. I didn't go often in August and so I covered all hours. But for the future I have to keep an eye on this matter. Starting very early is the best solution to that.
