'All Calum remembers is growing up in a peaceful settlement in the Isles on the edge of the North Sea. Across that icy sea, Lena has grown up the daughter of an Isles man taken as a slave in a Northern raid. As their two worlds collide, a spiralling cycle of violence, fear and bloodshed begins to engulf Calum and Lena. It seems that only by combining their fledgling knowledge of the Rune of Odin might they escape a terrible fate.' (Publisher's blurb)
