Perry Rhodan NEO: Volume 17 (English Edition)

While in captivity, Rhodan attempts to learn all he can about his captors, the Naats. He plans on using that knowledge to formulate a plan using psychic communication with his comrades in the hope of saving as many of the Tosoma's survivors as possible. But a power struggle is brewing among the Naats, and Novaal's leadership is unexpectedly challenged by an unlikely opponent, potentially upending the current order.

In a base on Rayold’s largest moon, commander Tresk-Takuhn does all he can to defend his lunar fortress against the assailants amid a stunning discovery made by his old friend Hisab-Benkh. With the fate of Topsid at stake, his efforts are desperate—but he has a few tricks up his sleeve that the Naats don’t know about. Meanwhile, back on Topsid, Manoli teams up with the Arkonide robot, Rico, to repair the mysterious transmitter and escape the despot once and for all.
