I’ve taken my first plunge into Kindlespace. My Marrion stories, which appeared in Analog, have been collected into a novella available on Kindle, under the name The Dark Forward. I’ve written an afterword, and also revised the third story in the trilogy after I decided the end could be improved.
Genetically engineered children is now a subgenre in SF. But these stories are unique in developing the idea of an engineered trait with a moral aim. The Marrion children are not engineered to be smarter or to be sleepless or to have any other trait of — shall we say — obvious commercial benefit. They are engineered to care more about the future. My conceit is that this would be a very important, and perhaps even very dangerous, trait.
