Star Trek: Ambush

The dilithium mining outpost on BorSitu Minor is an understaffed, uninteresting, unspectacular place full of miners, engineers, and scientists who have never done harm to anyone, nor do they have anything of value.

Yet the outpost has been devastated by a brutal assault, with almost all hands lost -- and the survivors have no idea what attacked them. Worse, the attack weapon appears to have the power to penetrate the outpost's powerful shields. That has the crew of the U.S.S. da Vinci worried, as it could just as easily destroy a starship!

The da Vinci comes across a strange runaway vessel that is giving off tremendous amounts of dangerous energy. However, the ship is not as strange as they think, as they've encountered it once before...

During the Dominion War, the U.S.S. da Vinci encountered this same vessel, and had to destroy it before it presented a danger to an entire star system -- not to mention to the war effort. However, doing so proved a challenge for the ship's first officer and second officer at the time: Commander Salek and Lt. Commander Duffy.

The Evorans, residents of a new Federation protectorate, have made a fantastic discovery on their homeworld: a device that predates their civilization and proves that aliens visited their world in the distant past. The U.S.S. da Vinci is sent to investigate the device and find out its true nature.

Before the twenty-fourth-century adventures of David Gold, Sonya Gomez, and the crew of the U.S.S. da Vinci came the more rough-and-tumble Starfleet Corps of Engineers of the twenty-third century. In the wake of an incident involving the Starship Enterprise and the infamous Delta Triangle, Lieutenant Commander Mahmud al-Khaled and the crew of the run-down U.S.S. Lovell must "open" the Triangle -- and also find a lost generation ship that was last seen entering the phenomenon. But the mission grows even more complex when the Gorn arrive, demanding -- at gunpoint -- that the Gorn criminals inside the Triangle be returned to them.

Dr. Elizabeth Lense has had a fine career. She was first in her class at Starfleet Medical - ahead of the genetically enhanced Julian Bashir -- and a hero during the Dominion War, and is now the chief medical officer on the U.S.S. da Vinci. but Captain David Gold notices that her performance has not been up to snuff. She's been listless and stressed, and is delegating most of her responsibilities to the da Vinci's Emergency Medical Hologram.

Her malaise couldn't possibly come at a worse time, because a virus has erupted on Sherman's Planet -- and the planet's entire population, as well as the crew of the da Vinci, are now marked for death by the virulent plague!
