Crisis at Starlight

"Whatever else the Frinn were, they weren't merciless killers. Jerome Walden was sure of that. The aliens had destroyed the research planet Delta Cygnus 4 in a cataclysmic explosion, killing thousands of humans--humans who had infected the Frinn with the deadly bio-engineered virus known as the Infinity Plague. The spacecraft 'Hippocrates', manned by the survivors, now pursues the Frinn to their homeworld--to annihilate them. Otherwise, they fear, Earth itself will be destroyed in a horrifying alien Armageddon. Walden alone believes peace is possible... and he may soon be an unwilling party to interstellar genocide."--Pg. [4] of cover.
