Assassin's Creed

Convict Cal Lynch is about to be executed for killing a pimp. Following, he regains consciousness to learn that he is technically dead but is under the "care" of Dr. Sofia Rikkin, who, working for a foundation whose scientific work is led by her father, Dr. Alan Rikkin, has devised a new technology for one to be able to inhabit ancestors through links in their DNA. The foundation has amassed a collection of people like Cal who have violence embedded in their DNA, Cal who watched his father murder his mother when Cal was a child. Cal apparently is the only connection back to Aguilar de Nerha, a member in a brotherhood of assassins in late fifteenth century Spain. The foundation's interest in Cal is that connection to Aguilar. They want Cal to inhabit Aguilar's body in a goal of ending violence in the world. As Cal proceeds to do so in a risk to his own life yet again, he has to decide what to do when the foundation has for him an associated goal of retrieving from the fifteenth century the Apple of Eden, then its last known time and locale, which has the key to controlling free will, that power which could be used for good or bad.
