The Pattern Ship

Zeke's on the run from government scientists who want a piece of him; and now an alien wants him too, or more precisely the piece of exotic meteorite that's moulded to his skull. To get it the alien has to get Zeke to give it up, but knows the extraction will kill the human. Then there's the Nubl, an enemy artificial species who will eradicate all biological life on Earth. Time and space are running out for all of them.
