When Bernice Summerfield finds human skull fragments containing her own DNA in the stomach of a mummified dinosaur, she embarks on a trail of murder and betrayal. From the alien jungles of France to the primal continent of Pangaea, the trail leads ever further back in time. Together with Patience, the cloned smart-raptor, Benny must brave alien hybrids, agents of the Knights Templar guarding a secret older than time — and have breakfast with the man who would be Emperor of Earth.
