Thrill Kings: The Gray Walls: Short, Interdimensional Sci-Fi

In‭ “‬The Gray Walls‭”‬,‭ ‬Nonstop and Krork battle an unusual inter-D in an office tower in Seattle.‭ ‬The creature may exist by devouring pockets of reality,‭ ‬and worse‭ ‬— it may have already devoured Nonstop and Krork.‭
Bonus material: an extensive afterword, and a proto edition of the “Thrill Kings for First Timers” sketchbook.
