Sell Your Nonfiction Book has been out for a few days now. The link will take you to the Canadian purchasers' page, where you can switch to US if you need to. I'll put proper links to each page in a week or two.
The Fall of the Republic
In a parallel timeline, 1990s America discovers the chronoplanes: parallel worlds at different points in history.
The hijacking of the Roman Empire, 100 AD, by 21st-century Christian fundamentalists, in the second of the Chronoplane Wars novels.
The Empire of Time
My first novel, published in 1978, but the last in the Chronoplane Wars trilogy.
"Write a space opera," my editor said. So I did, with some nanotech thrown in.
A companion novel to Icequake, set mostly in California.
A disaster thriller (Antarctic ice sheet surges into ocean), dated but still fun.
Originally published in 1982, and still the novel I'm most proud of.
