You remember the Firefly episode "Out of Gas"?

The ship has no power whatsoever... except for its artificial gravity.

Would it help all the prologue and epilogue haters if we just renumbered them Chapters 1 and [last number]?

Since our books are already published, could you, you know, just mentally do that?

Thanks!

A post-typhoon ravaged the West coast of #Alaska last week, and hardly anyone is talking about it. 15 villages got wrecked. Hundreds of people have been evacuated.

This link was provided by our Alaskan friend. We donated. Perhaps you can help?

Sadly. Silverbob is actually quite a good writer, but women have always been his weak point, and his work has aged poorly as a result.

"Up the Line" was poorly received even at the time, though I enjoyed it when I was a teenager. It is kind of a conscious parody of the genre.

My rule is if I have cash in my wallet from book sales, I leave big tips. The circle of artists.

By the way, I had a dream about you the other day! It was just a cameo. You were walking down the street.
