A Tale of Halley — R.J. Ziegler

EARTH YEAR 2129: HALLEY'S COMET plunges toward the majestic ringed planet of Saturn on its epic journey toward the Sun and its ultimate encounter with destiny...or disaster. The Vulpar have vowed to destroy the mighty Earth-Titan Fleet based on Saturn's moons, and Comet Halley carries their instrument of destruction. Three astrophysicists on an expedition aboard Comet Halley: Valerie Sagan, Dianna Cooper, and Heather Gault discover the deadly plot. When Cooper is taken prisoner by the Vulpar star ship's Commander Ruelot, Titan Command dispatches the cruiser Sceptor commanded by Matt Hogan, Valerie's ex-lover, to rescue Cooper and the Halley's Comet Expedition. Sexual tensions flare between the two star-crossed lovers as the crew of Sceptor battles to rescue Cooper. Three Vulpar Battle Cruisers block the path of Sceptor in a deadly clash beyond the Jovian system: the final outcome of which will determine the fate of Saturn, and Valerie's dirty snowball...Halley's Comet.
