A great story of a generation ship approaching a new planet (after over 5 generations) and all the last minute stuff that occurs. Our plucky hero is in officer school (despite being from a family where that’s not the norm) has to work some shit out to both keep himself and his family from getting in trouble, but also to solve a weird mystery about why the ship isn’t behaving the way it’s supposed to. A lot of deconstruction of the various kinds of class/caste privilege and how they might shake out over a multigenerational voyage.
