Pro-Tip: When using high-BTU heaters like the Tradesman 400, tank sizing is critical. A standard 100 lb cylinder may freeze up due to the rapid rate of vaporization required by a 400,000 BTU draw. For uninterrupted performance, always use a minimum 500 lb tank or manifold at least two 100 lb cylinders together.

Perfection!
Format: Paperback
I have read this before digitally, and this is just as beautiful in the physical copy. It arrived in excellent condition. This is my favorite Lovecraft story, and it completely lives up to all expectations. Gorgeous art, moody, faithful to the story, and very detailed.

What adaptations ought to be
Format: Paperback
An amazing adaptation of Lovecraft's classic story to manga that changes only what needs to be changed to make the story work in the new format. The plot is the same, the art is incredibly detailed -- almost too much so -- and the changes in the plot are done only to deal with the vast amount of pure narration in the original. And they're intelligently done. This is how to do it. If you liked the original Shadow over Innsmouth, I think it's safe to say you'll love this.

High quality manga adaptation
Format: Paperback, Format: Paperback
I bought this, along with several of the other paperbacks in this manga series. They are all the same height and width and fit nicely together on my shelf, which is nice. All of the art is incredible. Some really detailed and haunting images. Most pages are black and white, but there are a few awesome images in color throughout the book. The quality of the book itself is great, and it's made with solid paper (not too thin). As someone new to Lovecraft, I really appreciate these versions of his stories which I'm told are true to the original writing.

Best in the series so far
Format: Paperback
I have loved all of the graphic novels of the H.P. Lovecraft stories but this one is by far my favorite. The detail on character expressions nicely compliment the story and is a wonderful interpretation of the source material.

Perfect Adaptation of Lovecraft's Story
Format: Kindle
Gou Tanabe has been making probably the best manga/comic adaptations of Lovecraft's works recently, and this depiction of "The Shadow Over Innsmouth" is by far the best. Tanabe really captures visually what Lovecraft was conveying via the text of the original story. Innsmouth is decrepit and rotting, the locals are sinister, and the deep ones are hideous. And, as always, Tanabe's art is of the highest quality. I can't recommend this enough, and I eagerly await whatever adaptation he does next.
