In a post-apocalyptic future, Medina has become the last bastion of a humanity fighting the nightmarish and infectious creatures known as the Drax. The shield that protects the city won't hold out much longer, and humankind appears to be condemned. The only ray of hope is a "package" ripped from the Drax by the soldier, Karloff. This package is in fact 14-year-old Hadron, said to carry within her the Great Redemption. But will the humans manage to control this young girl's force?

An essential question hovers over this second volume of the Medina saga: what separates the humans from their adversaries the Drax? Karloff finally comes face to face with Boso 1, who will accept nothing less than Hadron and his unborn child. The conservator and Karloff agree to a meeting at the site of Alice, the nuclear generator that first spawned the Drax arrival, to hash out the terms of an unprecedented agreement. Meanwhile, Hadron has strong opinions, but whose side is the fierce adolescent really on?

The Drax contamination Karloff sustained in book 2 of the series continues to lie dormant in his body, while Medina battles mutants who threaten the city from the inside, and fends off ever-greater attacks to its exterior. The city's protective dome is at risk of total collapse. Kladia strikes off into the desert to find a better life, while Hadron, pregnant with Drax leader Boso 1's offspring, makes a bold decision that might alter the course of history...
