There is no end to the horrors that unfold before the eyes of Zagor, Cain and Princess Marada’s Tuaregs. After a miraculous escape from the fury of the ghouls, their well-earned rest in the Gebel Shaat fortress is but short-lived: hordes of living dead are thronging against the walls, a spectral army composed of the corpses of all the soldiers whose bones have been bleached, century after century, by the scorching sun of the Djouf. They’re being guided by two Kushite priests, and this is the pair that must be struck down! Meanwhile, the search for Jacques Lassalle is still proceeding, with not only Zagor and Cico following his trail, but Captain Jean Lafitte’s bold and headstrong daughter Denise too, as well as the guardian angels Jerome and Van Sutter. For all of them, the quest leads to the legendary reign of Songhay and its magnificent queen, but not all of them get there by the same route. In fact, there are some, like poor Jerome, who will never set eyes on the majestic walls of the jungle city.
