“While fans might know him from his adept handling of diverse superhero characters, they still might be surprise by the subtlety and suspense Underground #1 provides.Neither Lieber’s facility with “normal” humans nor his status as a superb storytelling craftsman are anything new, but he seems to be exceptionally matched with Parker for this project. The characters seem real, the pace subtly ensnares you, and the project is filled with potential.”
J. C. Vaughn ,Scoop.

“This is the way comic books should always be done; sharp dialogue, crisp art and dynamic colors all mixed in equal, complimentary parts. In case I’m not getting my point across, this is a five-star, two thumbs up kind of book that you really don’t want to miss. Underground #1 is my favorite single issue so far this year and I’m confident it’ll be yours. “

“I find the whole story setup very interesting. It highlights a very topical conflict when it comes to caves, that is the age-old commerce vs. conservation argument, and does so unobtrusively within the context of the story. Characterization is strong, as is to be expected from Parker.”

“I had the chance to read a preview copy, and I was impressed by how quickly I got to know and care about the characters, as well as the (literal) cliffhanger. I can’t wait to read more!”
