The Pulldogs leave Rome to embrace a new condition: leaving no trace of their passage, they shape a new challenging lifestyle: wandering around the world as neo-nomads to spread their solarpunk way of living and to engage on a never-ending mission to save endangered human cultures with nanites.

But the vision of Alan and Nicolas about how the Pulldogs should live collide, and as a consequence, they split in two groups: one goes North to live in the beautiful wilderness of Siberia and Mongolia, while the other goes South to save the Dogon tribe from a possible extinction due to climate change in Central Africa. But at the end everybody - including a new generation of Pulldogs - will have to come back to Rome, where their incredible transformation started many years before. Sequel to the celebrated The Roamers.
