Before Crowbar can complete the repairs, Vondar, Malvanna, and Torvek attack, crippling the station allowing them to steal the satellite, which continues to malfunction and firing at random.
Emperor Daark releases search and destroy probes to eliminate the research stations which are interfering with his Jupiter studies. Dash's mother, Amanda, and sister, Lianna, are part of the research team. Sighting an incoming missile, Lianna shoots an anchor into an airwhale and the station is off on a "Nantucket sleigh ride," so-called from the past when whaleboats harpooned whales and were dragged for miles.
Slim, Dash, and Crowbar experience a few diversions while trying to deliver a new security computer modem to researchers on Ganymede Colony. Malvanna plants a cyberbug in Crowbar which enables her to see and hear everything Crowbar does. StarCom joins a supply convoy hoping to mask the importance of their mission but things keep going wrong hindering their journey until, oddly enough, the security system shuts down right after Crowbar says how it can be done.
Torvek is massing drones on Io, the volcanic moon, for an all-out surprise attack on StarCom. Suspecting this, StarCom is forced to set up a base on Europa, the frozen moon, where a young scientist has just discovered what he believes to be an intelligent life form. Dash, Crowbar, and Slim decide to hit Io in a surprise attack in order to protect the explorations on Europa, but Torvek's massive forces catch them unaware.
Emperor Daark stumbles across plans for controlling electromagnetic pulses and immediately puts it into use.

The Verdugo Commune, a successful and peaceful farming community is besieged over and over again by mercenary raiders who consider these people ripe for the picking since they are passive and do not fight back. Slim, Dash, and Crowbar chase them away for the moment, but are told to leave by the elders who dislike fighting violence with violence. Our guys still try to help, though, but the people, with Dash's lead, defend themselves by using the gigantic mirrors in their valley to blind and confuse the raiders.

He puts Hatch under arrest and this distracts his attention long enough for a real Shadowbat to get close.
