I expect the back to change as more people read the book. They will say things like “J M McDermott is awesome. He paid me to write this. I was promised beer!”
I may not have a large shelf o’ glory, but much of what I publish in short stories is in on-line markets, where the readers and money are at, and I’m only 30. I turn 31 in December. I think, perhaps, I’ve got a lot more books to write. For instance, the two sequels that are contractually obligated (and in progress–no worries, party people! I will meet my deadlines!) will must be added.
