Fresh from her tour of duty on the Enterprise, Dr. Pulaski is summoned to the Cardassian outpost of Terok Nor (soon to be known as Deep Space Nine) to help diagnose and cure a plague that is affecting both the Cardassians and their Bajoran slaves.  When she arrives, she finds that the cause of the plague looks awfully similar to something the Enterprise had encountered a year earlier.

Dean Wesley Smith and Kristine Kathryn Rusch bring us Vectors, the second entry in the Double Helix series.  Now, I can’t say I was particularly thrilled to find out that this was basically a Pulaski solo story, away from the rest of the Enterprise crew, but it turned out better than I would have thought.  There was some plot overlap with the previous entry, but I guess there are only so many ways to investigate and solve for a mysterious plague affecting a population.
