The Shapes of their Hearts was originally published by Tor Books in 1998.
On the planet Idun a computer tape of the uploaded mind of a religious prophet has been allowed to merge with an AI. The result is both a Christian icon—a godlike being venerated by the faithful—and a powerful religious terrorist in its computer avatars off-planet. This is a god of whom many copies exist. Anton Tso’s challenge is to stop the terrorism without killing God.
