The second volume of Meaney's epic Ragnarok space opera trilogy. The dark matter in the universe is alive and is seeking to pervert human history to its own ends. Its influence has reached back into the dark ages, to the centre of the 3rd Reich and 600 years into the future. The Ragnarok universe not only provides a stunning SF rationale for Norse mythology but posits a world where pilots are locked into symbiotic relationships with their ships and the cities can come alive.
