The Hammer and the Cross

The story begins with Shef as little more than a thrall in his stepfather's service. When he is not busy with mundane tasks, Shef finds himself aiding the village blacksmith, where he develops his talents as well as an affinity for invention. A Viking army invades, and Shef's stepsister Godive is taken during a raid on their village. Shef and his friend Hund proceed to the encampment of the Ragnarssons, leaders of the invading army. Rising swiftly in and beyond the Viking army, Shef's greatest task becomes defeating a new invasion.

In a review, the Science Fiction Chronicle called the book a "swift-paced, historical science fiction story with an air of absolute authenticity. This is the way it might have, and perhaps should have been." A review in Runepebble called it "an interesting alternate history" and recommended it for older children as it was "violent but not without cause."[2]
