"She was dead when I got there," Mom casually said
Format: Paperback
I've faithfully followed Living the Line's Smudge manga releases up to this. Actually I had this one preordered for ages but Amazon never shipped it to me and I only noticed it was in stock by chance. I had to cancel and reorder it. What the heck, Amazon?
Anyhow, it's definitely a horror story but also a species of superhero story, or at least a person-with-superpowers story, without the encumbrances of lore, heavy character- or world-building, a continuing narrative in a shared universe, or anything else. There's really nothing you could call a plot. Stripped down and even rough as it is, it's utterly engrossing, surreal reading for me.
A lot of my manga reading is horror but I've also been enjoying superhero manga like this or, for example, Hikari-Man FAR more than anything from the Big Two because of the greater freedom the Japanese works exhibit in how they conceptualize power(s) and heroism.

Awesome graphic
Format: Kindle
This graphic tale is engaging, thought providing. Leads you into taking another look into the events of the past as you grew up in the 60s, 70s, and 80s. Cool blend of a crazy bend of history, horror, and secret organizations of control.

The Truth

A good beginning
Format: Kindle
This is a difficult book to review because just as it really gets going, it ends. But I like the direction it is headed. The writing is solid and the artwork is gripping. The point it appears to want to make is that conspiracy theories can be dangerous. There's truth to that. But there's far too much fact in many of them to simply chalk it all up to an overactive imagination. So that danger exists in this story to want to think conspiracy theory is all nonsense (and this story seems to place the blame for all conspiracy theories entirely on the "right wing" which is shortsighted). But this quibble aside, the book is compelling. Where it will lead is up in the air. This could be a great beginning to an excellent story, or it could fall apart under its own gravity. The future will decide.

Not your typical tale…
Format: Kindle
Great writing, rather mesmerizing in its way. The mixture of deep state conspiracy, a smattering of actual truth, and mythical freely pull you in.
The artwork is a bit over the top at times; I see the intention behind this, but it harms rather than helps the story at some points. This abstract/high concept art crap could have seriously been dialed back and then better assisted the narrative.
Not to say that this isn’t worth the read… I gave it 5 Stars because the tale itself is well told and very riveting.
