It's actually a complete 5,000 word short story, and was first published in 1985 in the Baen Books 'Far Frontiers' bookazine. It should give you an idea of what you're getting into while deciding whether to give the novel a spin.
I hallucinated the central concept when I was fast approaching a writers workshop, and was feverishly trying to come up with an idea for a story, because I didn't much want to be humiliated in front of my peers. Well, no more than usual at that sort of event.
I realized soon after finishing the story that I knew more about the characters in it and what sorts of adventures they might have. So I started nibbling at writing my first novel. It took about three years.
I brought the completed manuscript to the Space City Writer's Ranch workshop in Houston, where it was viciously shredded by other writers who are mostly still my friends. I made a few minor changes...
I then sent it to Tor. Turned out that they were trimming their author's list that year, and it was returned unread.
Baen got it next and semi-promptly bought and published it. Now it's back.
I'm proud of it. I think I did a pretty good job on it, and I believe that it doesn't suck. Despite a somewhat whimsical cover, it treats its characters seriously, and it's got some romance and adventure. And some fightin' and a fair amount of stuff getting blowed up good.
Robert Heinlein famously wrote that us writer types are competing for our reader's beer money. I'll make the deal with you that I made first time out, to everyone who I've spoken with about it.
If you buy the novel and genuinely feel like you didn't get your beer money's worth, I'll PayPal it back to you.
I'll also pay postage for you to send me your copy, because, well, hey, I'm collecting the darn things. It's a relatively small print run, and I'm betting they'll be worth a million – no, a billion -- dollars at some point in the future.
Incidentally, and completely unrelated to the above, I'm a marginally-competent recording musician. And a zombie freak.
I'd be delighted if you check out a couple of zombie-themed songs I've done. Free, of course. Man, I love this rock 'n roll lifestyle.
