And here’s John Birmingham on Final Impact, the last book in his “Axis of Time” trilogy:

You know that feeling you get when you finish a book and you just want it to go on, because you've grown so close to the characters. That feeling is about a hundred times worse when you wrote 'em. Sure, you mighta done 'em some damage in the story, even a killed a few along the way, but still it hurts to let go. I thought I'd finish this trilogy and leap into the air shouting “Free at last!” – but I didn't. The characters had become my friends and I was sorry to see them go. 'Cept for Himmler of course. I was happy to put the zap on that crazy little ratbastard. I hope you come to feel the same way.
