Dr. Pretorius leads Geneva and Noah through a Topside blizzard to his secret research lab. Armed with the PH-Ts and Dr. Pretorius' new Silverwing device, which will defeat Tao's Electronets, Noah is ready to take Geneva back to Haven. Arriving, they stare in awe at their surroundings, it is the ocean and it is truly magnificent. Turning at the sound of a familiar voice they are stunned to discover that Becky has somehow managed to accidentally travel with them. After a rest, good food, and the company of the Sandtribers, the trio commence their journey home. Coming across an Electronet, Noah makes a discovery that will have serious consequences — Tao has activated the nets but the Silverwing weapon is faulty and ineffective against them. Arushka calls a meeting to determine Ferris's fate within the Nomads. It is decided he can join them if he can convince Tao that they do not believe he is installing any more Electronets and is abiding by their truce. Tao doesn't believe Ferris for one moment. With Becky's help, repairs are made to the Silverwing and its test comes when the Nomads discover Tao has targeted the horses as his first victims. Noah and the Nomads can only hope that the Silverwing will work. Noah throws it, it flies through the air, passing through the nets and returns to land at his feet. The horse escape unharmed through the Electronets. It has worked! They are triumphant! (thetvdb.com)
