A Fragment of Destiny — Richard Turner

In 1918, a German U-boat on a clandestine mission to the United States vanishes at sea.

Ten years later, Christopher Sheppard finds himself thrust into a deadly race to find the truth about the missing submarine and why someone is willing to risk it all to stop him. From New York, to Europe, to Greenland, Sheppard must keep one step ahead of a man, blinded by grief, who will stop at nothing until he has his revenge.
