answer:This happens often with long series, especially if there is a long gap between releases. The publisher wants the new releases to appear “fresh”, and they don’t particularly care if the later jackets match the earlier ones – because if the customer cares, they will buy the older titles over again to get a matching set. The Bantam Spectra series that is currently available in the US under non-HBO jackets looks like this. Assuming that you are in North America, you can choose either these covers or the tie-in covers. If Bantam has discontinued the “shiny” ones you started with, you won’t see them again. If you’re not in NA, they might have a different look, depending on which country it is.
