Wolf in Shadow (first published in the United States as The Jerusalem Man[1]) is a 1987 post-apocalyptic heroic fantasy novel by British author David Gemmell.

[2] Initially written as a stand-alone novel, Gemmell expanded it into a trilogy consisting of the novels: Wolf in Shadow is set in the future, three hundred years after the "fall", an apocalyptic event of which little is initially known, but which is regarded in the book as an event akin to Noah's flood in which the world shook out of its orbit tilting it on its axis, which subsequently resulted in the oceans rising and destroying most of human civilization.

Additionally blood Sipstrassi inspire darker feelings such as lust, greed, and rage in their wielders.

[5] Of his criticisms Gemmell only mentions the line "I dread to think of people who look up to men like Jon Shannow.".

This review in particular led to the introduction of a character Josiah Broome in subsequent novels, who allowed Gemmell to show a contrast between Shannow, a man unhesitating in using force to combat what he saw as evil, and Broome a man who regarded the use of force as an evil unto itself.
