There have just been SO. MANY. CHARACTERS. since Death in Winter. I thought Beyer's Voyagers characters were integrated seamlessly into the crew, but there hasn't been a clear and consistent voice in the TNG novels to bring many of these characters to life lately. It seems like every time we start to get to know a character, they're killed off.
Miranda Kadohata was interesting. T'Lana was interesting. Leybenzon was interesting. I was finally starting to like Choudhury too. Why did they have to go and do that to Worf again?
mrhová and Elfiki are just names.
