I have read a couple of the Wayfarers series. I liked A Closed and Common Orbit, but The Long Way To A Small Angry Planet didn't work very well for me, personally, and I haven't kept up with the rest of the series since. I might have to give them another try!

Prince Borghese's Trail looks really interesting though, and it looks like there are a couple of used editions available! I've heard a little bit about that race (I think as an anecdote in a different book), but haven't read anything that focused on it.
