The ending of 'Paths of disharmony' could go either way: Making the andorians leave the federation could actually be beneficial for the andorians (as a species in the trek franchise), in the sense that it would bring them to the forefront, provide future books with something of substance to develop and, thus, assure future in-depth development for them - as opposed to the relative neglect the species suffered until now. This would be a 'gutsy' choice. Of course, at the end of the book, the andorians could remain in the federation, in tune with the 'rebuild' optimistic theme authors claim, on this site, will characterise future trek lit books. Will they still be dying in this case? Most likely yes; this is one of the few particularities of the species that can be interestingly used in the future.
