Winter AD 103. Fourteen years have passed since Corbulo's murder and Marcus, veteran soldier of Rome, sets out to avenge his father's death and to find Emogene, the druid who holds all the answers. As he closes in on her, Marcus must decide how far he will go for honour, and whether to follow Emogene to the secretive and mythical land of Hyperborea, an epic sea voyage across the Atlantic ocean.
