Star Wars MedStar I: Battle Surgeons. A Clone Wars novel.
It wasn't bad but there wasn't too much action in this one. I think it was building up for the second novel. Though there is a cool fight scene between a Sakiyan Admiral and Nediji Assassin. The Nediji wins by poisoning the Sakiyan using a knife coated in Dendriton poison.
Dendriton toxin
"Dendriton toxin is a bad way to go. Painful, slow—you're literally immolated from inside out. But you were a brave adversary, Admiral, and I admire bravery. So, even though my superiors wish you to suffer, I'll spare you the toxin's effects."
―The Nediji assassin Kaird kills Admiral Tarnese Bleyd[src]
Dentriton toxin was a type of poison to which members of the Sakiyan species were susceptible. Soon after exposure, the toxin caused fatigue and lethargy. It then manifest as numbness, eventually leading to intense muscle pain and total paralysis. The Nediji assassin Kaird laced his knife with dentriton toxin before a fight with the Sakiyan Admiral Tarnese Bleyd. After a cut to his hand, Tarnese succumbed to the effects of the toxin, allowing the Nediji to kill him.
