An excerpt:
One thing I like is that at no point does Lucero even consider the possibility of killing the tribbles. I’m sure many of them do die when the superstructure of the ship collapses, but it’s established that plenty survived, at least. The only fatality is Larkin himself, but tellingly, none of Starfleet’s attempts to restrain the tribbles are lethal: their phasers are on stun and they’re never consigned to space via an airlock.
