For those who like their near-future sf/mythology fantasy with an explicitly Christian element, "Wolf Time" is the book for you. Following in the tradition of the literary social prophets, such as Orwell, Huxley and Bradbury, Walker joins the growing ranks of Christian apocalyptics, such as Michael O'Brien's "Father Elijah," Frank Peretti's "Piercing the Darkness," and Bud MacFarlane Jr.'s "Pierced by a Sword."
Carl Martell, history professor at the non-Christian Christiana College, cannot tell a lie. But he can sense when others do. And when acclaimed Norweigan Poet, Sigfod Oski, comes to town, Martell is certain the greatest deceiver of all is in their midst. Peopled with such endearing characters as the quiet but courageous Lutheran pastor, a born-again disk jockey, and the mythological wolf, Fenris, "Wolf Time" pulls you into Walker's all-too-realistic vision of where America is heading, and what believers will be called upon to endure.
Like almost all novels with an agenda (Christian or otherwise), though, the prose sometimes suffers for the Bible verses scattered throughout. Every conversation between two characters revolves around culture and religion, which single-mindedness may put-off would be readers. However, Walker's insights are sound, and his morals excellent - and, better, both are handled with a greater delicacy and tension as the book progresses. Walker is not afraid to present all sides of the argument, to make witches sympathetic while arguing against their theological view, to examine the fundamentalist fanatics' reasoning for fighting fire with fire while showing Christs' equally decisive but remarkably non-violent solution.
Christians, especially Lutherans, will enjoy Walker's take on the near-future. Viking and Norse Mythology enthusiasts will find "Wolf Time" an intelligent look at that religion. Recommended to teenagers and adults, due to several references to sex and violence. People searching for a follow-up non-fiction work may want to check out Peter Kreeft's "Ecumentical Jihad."
