I originally read Sandman Series while working at my local B&N. It was the recolored four-volume Absolute hardcover edition with slipcase. I pretend to re-shelve the one set in the store everyday. Reading while hiding corners from co-workers, ignoring customers and barely working lost in the pages. Reading about the Lord of Dreams while trapped in my version of Hell gave me hope.
Recently, I bought the trade paper version on impulse, and still love it. Gaiman himself has summarized the plot of the series (in the foreword to Endless Nights) as “The Lord of Dreams learns, one must change or die, and makes his decision.” And so must we.
