This particular volume offers much that will please long-time fans of the series. The Three Graces (or Fates or Furies or whichever mask they wear at this moment) make an appearance and a few references are made to other aspects of the series lore. Perhaps the most exciting of these involves us discovering the origins - or at least one version of the origins - of Dream's sometimes=seen but rarely mentioned lost-love Alianora.
The only reason one might have for not reading this series is having not already read Neil Gaiman's Sandman before now. If that is the case, you would do well to travel to your closest library or bookstore and make arrangements to get a copy as soon as possible. Then, once you are all caught up and have ceased thy wailing about how foolish you have been to have lived so much of your life without experiencing such bliss, you can read this series.
