Talented young architect David Gordon suffers severe migraine headaches and visits a psychologist to learn self-hypnosis for pain management. During his next brutal attack, he experiments with the new therapy, but something goes horribly wrong. He is transported through shared DNA into the mind of a 12th-century ancestor, likewise a migraineur. An avid genealogist, David knows the immediate future of these people. He decides to warn the youth that an ally will betray and kill his father to steal the fertile lands of Raven’s Crowne, located in the Scottish Borders. When the prophecy comes true, the boy and his brother seek sanctuary with a sympathetic Knights Templar preceptor with secrets of his own. The battle for justice involves a withered seer and her young protégé, a wily bishop with little tolerance for the old ways she favors, and the ailing King of Scots. Can bonds of honor and love defeat an implacable and devious enemy? David Gordon worries that contact with the remote past might affect the future, but he must obtain his ancestors’ help in returning to his own body and time—without leaving an indelible, and perhaps disastrous, mark on history.
