It's a tricky question, but I think that this should be the starting point for anyone new to the Galactic Milieu/Saga of the Exiles world. Oncle Rogi gently introduces us to a developing world - May cleverly foresees many technical developments - and sets the scene for the events of the Saga. But then, after you've read the Saga of the Exiles, you'll want to come back to this book to see what happened next - or is it before? Whichever way round, read these smashing books. They have warm, developed characters, thought-provoking ethical discussions and sex with aliens in pschedelic tanks. What's not to like?!
