A light, fun read, with less awkward diplomatic situations than "Failure to Communicate" had but more awkward romantic situations. Xandri and Diver took turns narrating, and I wasn't much of a fan of Diver's narration - he tended to notice the same things as Xandri and use similar language to describe them (exception: Xandri from the outside), except with a lot of "this narrator is a male man guy, by the way" insertions that felt pretty otherising - but there's some neat worldbuilding, and I appreciate the presence of a "the space whales are not technically whales, though" pedant in a sci-fi story with space whales.
