This is the fourth in her "Retrieval Artist" series, and the quality has held up throughout the series. There is one more book that follows this one. They are best read in order, because the later ones generally assume you've read the earlier ones.
The series is set in the future, when we've colonized the moon and have encountered many other species, and are trying to maintain a relationship with all of the different alien cultures. The setting is the Moon, and her descriptions of the domes that make up the city of Armstrong on the Moon are so vivid I think I could step into that world. I love the details about the food, the buildings, and the government. Her characters are also pretty well rounded.
These are a quick, light read, and quite enjoyable.
