Sons of the Morning is Dewitt Copp's most complex and fascinating novel to date. Fifty years ago, a team of scientists hunting fossils camped out by a Canadian wilderness lake. They vanished, leaving only remains of the camp and the diary of their leader, Dowd, with its strange, indecipherable diagram.

In subsequent years Dowd's mysterious document drew the hunters: Montour, the bush pilot, stole it, certain it would bring him the freedom he so fiercely sought. Jason, the British SOE agent on the run, killed for it, believing he had seen its duplicate in France. Von Werbel, the crazed German genius, plotted to use its markings to bring about mass destruction. The invidious Stanhope, of the Ashdom Foundation, kept the diary secret against the day it would make him famous. Now it is Dowd's haunted daughter, Kate, who flies to the deadly lake to find what Dowd's diary described as "a discovery like no other" and, in doing so, uncovers the real meaning of evil.
