Double Helix Omnibus - Couverture souple

For over a decade unknown enemies have unleashed a string of deadly biological weapons throughout the Alpha Quadrant. Not only the Federation is at stake. The plague threatens first Romulus, where Vulcan Ambassador Spock calls upon his old friend Dr McCoy; and then the Cardassian space station Terok Nor -- later to be Deep Space Nine -- where Prefect Gul Dukat is forced to work with Federation doctor Katherine Pulaski and rebel spy Kira Nerys to save those under his command.
Meanwhile Captain Picard and his crew join forces with Captain Mackenzie Calhoun of the USS Excalibur to confront the hidden architects of the virus and avenge the deaths of thousands. But the truth is closer to Jean-Luc Picard than he knows. Its seeds were planted ten years before, when, as captain of the USS Stargazer, he was caught in a conflict between two hostile races. Then, Commander Jack Crusher of the Stargazer and Vulcan officer Tuvok teamed up to investigate the conflict, unaware that their intervention would breed catastrophic consequences for the future...
