Sounds wonderful. I recently had my writing—which is liberally sprinkled with em-dashes—edited to add spaces to conform to the house style and this made me sad.
I also feel sad that I failed to (ironically) mention the under-appreciated semicolon; punctuation that is not as adamant as a full stop but more assertive than a comma. I should use it more often.
I love great book covers and have great fondness for the covers of novels I love however I buy most books online and by reputation or review so rarely see a cover that arrests my attention.
