Note the description:
The most demented, nefarious, ghostly mind of the new millennium must be stopped, but the grand scale of his plan is out of reach of the authorities. A desperate military contingent will unite with civilians in a final attempt to prevent the worst. Will they succeed?
This is really a shame. As-is this wouldn’t be a half bad dimension-hopping sci-fi cover. The concept is rock solid for a book like that.
At least the shadow could have been going in the right direction.
Crap, totally missed that.
Unless your first thought was correct and it’s inter-dimensional (cue Twilight Zone theme).
