Nightshade by Laurell K Hamilton

The excerpts detail a tense diplomatic mission by Captain Picard, Counselor Troi, and Lieutenant Worf to broker peace on the dying, war-torn planet Oriana. When a Venturi general is poisoned, Picard is framed for the murder and imprisoned, forcing Worf into the role of acting ambassador while Troi uses her dangerous empathic senses to investigate. They discover the Orianians keep severely deformed newborns as "lifeless children" in vats, while hating the third faction, the Greens, for possessing superior healing biotechnology. The true killer is revealed to be Torlick General Basha, whose deep prejudice and hatred for the Greens drove him to murder his rival and frame them, shattering his own family in the process. Simultaneously, a parallel narrative follows the Enterprise crew assisting a damaged alien ship and discovering that its organic engines are alive and were intentionally sabotaged by one of its own officers.
