It says here, “Write a story”. Well, with Ian Stewart I wrote one, and it’s just about published. (The ebook is available from the publisher, but the links to Amazon for the ebook and paperback, not quite yet.) First novel at age 71… guess I’m a slow developer.

Stephen Baxter says “Classic science fiction: a startling and original premise, a character-driven plot exploring that premise with great imagination and ingenuity… Recalls Niven at his best — with better science.” So you know it’s aimed at geeks. If you are a true geek, you’ll enjoy picking holes in it.
