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!
They are definitely not literary or hard sci-fi, but I can’t deny they are very fun to read. Reminds me of watching Firefly in a way when it first released.
