Things perked up because I actually managed to do something useful and productive later in the day. This may or may not be a long-term positive thing but in the short term it was great.
The day ended spectacularly well though. I was just about to go to bed for the night when my phone beeped. I thought it was an SMS but no, it was an email (I really must give them different tones!).
The email was from my publisher and included a rough outline of the cover for Blue Jackets III. Based on the two sentence brief I gave the artist nailed it!The actual finished cover may not bear any resemblance to the sketch but it was enough to cheer me up and help me move on with my day. Have a sneak peek!
