If you think you can unlock the gates of Hell and just invite yourself in, you must be Dreaming!
The Sandman Universe crossover begins here, with this specially priced re-introduction of the storylines and characters who populate next month's landmark event series.

First, in the Eisner-winning Locke & Key tale, "Open the Moon," meet Chamberlin Locke, patriarch of the Locke family, whose Moon Key began to unlock the events of this event series.
Next, journey with the Lord of Dreams to Lucifer's domain in the chapter of Sandman's epic "Season of Mists" storyline that sees the Key to Hell change hands in a most momentous way.

And join IDW and DC Comics next month for Locke & Key: Hell & Gone #1 by L&K co-creators Hill and Rodriguez!
