I like these kind of one-shots with one-and-done short stories. They give you a satisfying taste of iconic characters without all the weight of their massive backstory or ongoing continuity.
“An all-new, all-creepy one-shot set in the DC Universe-just in time for Halloween. Martha Kent fights for her life against a creature from a spacecraft that lands in front of her farmhouse. A young woman is possessed by the spirit of a murderous Amazon warrior. The last surviving member of the Justice League faces down a horror beyond imagining. All these and more are what happens when the most exciting new voices in contemporary horror fiction are paired with the talents of some of the greatest artists in the DC firmament. And if that isn’t enough to scare you, there’s Keith Giffen, too.”
