Partnership is about Nancia. On her first trip, she transports several young people from high families. Unfortunately, they are all corrupt and she overhears their plans, but is persuaded that she shouldn't have, since she didn't identify herself as a brain ship. Her first brawn happens to be extremely stuck up regarding his morals, so it takes a while before the situation gets rectified...I liked this book a little less. It was still entertaining, but I was annoyed by the moral brawn, and Nancia herself at first agrees with him. Fortunately she loosens up later on. The book followed the young criminals quite a lot, and this was ok, but I still would have preferred reading more about Nancia. I did like the descriptions of Singularities and particularly the Singularity incident that Nancia has to get out of later on in the book.
