Last week, I got an envelope from my publisher. The first few times, I ripped them open excitedly, trying to figure out the numbers. Book-selling numbers are very difficult to make sense of, and I know this is not just me because every single author I've talked to has rolled his or her eyes when I asked how the hell to read a royalty statement.

"Just wait for the check," said one and went to get another drink at the bar.

"Start your next book," said another, and he laughed and laughed and laughed.

While I was working on my next book and waiting for that check, I attempted to predict out how likely it was I'd ever get one. Not everyone does. In fact, rumor has it that most authors don't earn out their advances. I don't know if this is true or not, but that's what the Internet told me.

The more I learned about returns and sell-ins and sell-throughs and discounting and backwards numbers, the less enthusiastically I ripped into those envelopes. I think there was one royalty period when I didn't even get an envelope.

Then ... this envelope. The numbers appear to have started over, and they're from December. And there was a check in there. A royalty check.

And so of course I started jumping up and down and screaming. My parents and sister were here for the weekend and everyone looked at me in confusion, trying to decide if I'd finally snapped or what. I tried to explain the backwards numbers and the confusion and frustration of trying to figure out what was going on with the book, and then I gave up and just kept jumping because that's okay, too. Beloved says all the time it's enough for the book just to have been published, but to me it wasn't enough. I wanted it to earn out.

I don't know if it earning out meant financial success for my publisher, and it certainly doesn't mean I can quit my day job. It was just really important to me. It means it was worth it to sit there at conference signings two years after the book came out, when people came up to me and said essentially, "You're still doing this?"

It gives me more energy to write the bio and marketing plan I was advised to write to go along with my novel query. Because this book business has such high highs and such low lows: I need all the help I can get.

It was a big help.
