I’m reading them in the author’s recommended reading order and I’m currently up to The Vor Game. While the first Cordelia books are decent the Miles books are real page turners so far. So if you were put off by the cheesy looking covers like me, give them a go!
I love them, they are so engaging and the different cultures are distinct in understandable ways, the plot hangs together, they are good books. Not like hard sci fi but effortless placement of a dramatic story in a different universe.
