DC Event - Dark Nights: Metal - Complete Reading Order (NON-SPOILER)

I. BACKGROUND READING

* Batman Vol. 1 #452-453 (Jun 1990) (YOU CAN SKIP THIS!)
* Batman Vol. 1 #454 (Jul 1990)

Suggested reads:

** Hawkman and Hawkworld Reading Order (1989-2013) - Suggested read after this event, to explore more of Carter Hall, the Hawkman, as he is also one of the main characters like Batman, where the story revolves around in this event. And there is no use of reading Hawkman: Endless Flight (2003) (TPB) alone, which collects Hawkman Secret Files and Origins #1 (2002) Hawkman Vol. 4 #1-6 (2002-2003) as some website suggested, as it does not gives any completed basic idea related this event, but after compete reading of this event and if you have time and interest to know more about Hawkman, read Hawkman collections, I am damn sure those Hawkman collections will give amazing reading experience and how his complete life is related to this event.

** The Sandman Vol. 1-3 (DC Vertigo) (1989-2015) - Suggested read after this event, as it is directly related to this event's theme and also gives clear idea how it is indirectly related to this event itself.
