To be truthful I picked this up from the library because I thought it was going to be about Odessa, Ukraine, and I am trying to read more about that area, literary tradition, and so on, but it's really not. A post-apocalyptical story that uses one color, pink, the same one-color I recall François Vigneault using in his fantasy/sci fi series. It is Jonathan Hill's first solo effort (he has illustrated others), and he said it took home basically more than ten years to come to publication. So from one author to another, or from any readers to a persistent writer, he gets points for this.
The story reminds me of another comic I just read, Snow Angels by Jeff Lemire, where the kids are suddenly on their own braving the great unknown, the wilderness, without adults, which is one version of a coming-of-age story, or orphan story (Oliver Twist, and so on).
The set up: Earthquakes have completely destroyed much of the American West, so there are some survivors encampments, raiders for remaining resources, and so on. A guy raises three kids after his wife left eight years ago. She gets a package with a letter from mom and they leave Dad to find Mom. This is, we discover at the end, is To Be Continued, so that is disappointing, as the story actually feels long already, and not all that eventful, really. But I like the artwork (though 300 pages of pink is a little over the top). But good for you, Jonathan. I wish you all the best.
