The War of Retribution against the city of Juarez has gone well through the autumn and winter months and with spring nearing the conflict between the two mafia cultures is coming to a close. Fiona, at the head of a fresh army of Ravens provided by the new White Queen Alondra, has captured or killed the fleeing remnants of the Juarez invaders responsible for the massacre at Tombstone. Supported by Gieo and her fledgling air force of modified World War II planes, Fiona is set to end the War of Retribution with a decisive victory over the last bastion of the Juarez drug cartel. Before the final blow can be struck, the Slark make their return to the conflict, restored to their former glory and strength, using the terrible weapons of invasion everyone thought destroyed.
After a disastrous battle, Fiona’s army is on the verge of breaking and Gieo has fallen into the hands of the marauder warlord General Mackenzie. Fiona must leave the Ravens to find her captured beloved, riding out into the desert with her trusty scout and sidekick, Maude, to seek help from the revived Apache Nation, the spirit world, and Gieo’s robot companion, Ramen, who is discovered to be of sinister origins.
Riding through the post-apocalyptic world of West Durango, Fiona infiltrates Mackenzie’s marauders only to find the Ravens have once again lied to her. Fiona’s rescue might end in wedding bells and children or betrayal and massacre—it seems destined for bloodshed either way.
