Ancestor

Scott Sigler is the voice in modern horror - and ANCESTOR is the book that will have you checking under the bed... and starting at every bump in the night. Cancer. Obesity. The flu. Old age. They can all kill you - and modern medical science hasn't ever found a cure. Until today. On a remote island in the Great Lakes, an unusual group of scientists are using extinct DNA to create the perfect organ donor.
It could save millions of lives and win Dr Claus Rhumkorrf the Nobel Prize he craves. The donor animal is genetically the ancestor of all species on the planet - but Nature wiped it out two hundred million years ago. Rhumkorrf and his team are about to find out why.
