"The Dead Show" is an anthology building on the zombie lore as established by classics such as "Night of the Living Dead," and expanded upon by "World War Z" and "The Walking Dead."
Like the aforementioned tales, these shorts are not really about zombies. Instead, they're an exploration of survival and the human condition.
Ready yourself for an international array of zombie-ness, to include:
Necromancers Bio Hazards Zombie-Slayers Desolate Wastelands Wizards Political Dystopias...
Various is the correct author for any book with multiple unknown authors, and is acceptable for books with multiple known authors, especially if not all are known or the list is very long (over 50).
If an editor is known, however, Various is not necessary. List the name of the editor as the primary author (with role "editor"). Contributing authors' names follow it.
Note: WorldCat is an excellent resource for finding author information and contents of anthologies.
Typically, I do not like zombie anything (books, movies, series), but these tales were engrossing and enjoyable. I found myself looking for the hidden references, small bits of nostalgia woven into most of the tantalizing tales of survival. Buffy, peaches, etc., were all nice touches of normalcy in the various renditions of a zombie apocalypse. Well done.
