Oceans are rising, presumably the result of global warming. Somehow chemicals dumped into the sea cause genetic codes to be smashed, resulting in a new breed of monsters swimming to shore and eating people. The surviving humans are mostly enslaved by the elite, in the form of scientist-warlords. A dude named Simon steals a magic mask that empowers the saintly wearer (if donned by someone who isn't saintly, the wearer's head implodes). Simon befriends a prostitute named Orchid and meets a crazy old lady who lives in the Wild. Simon's goal is nothing less than revolution, class warfare that will pit the slaves against the masters, but his first step is to free Anzio, the rebel leader.
If you ignore the fact that the whole monster angle makes not the slightest bit of sense, the story has an appealing mythical quality. You also need to ignore the fact that cars and most mechanical devices haven't survived the devastation, but somehow "reflective bioheat panels" have been salvaged to illuminate tunnels and robots continue to operate factories. Assuming a powerful willingness to suspend disbelief, however, Orchid consistently entertains. The story is imaginative, the writing is a step or two above average, and the art is impressive. The coloring is especially noteworthy.
I would give this 4 1/2 stars, deducting a half star for the mutated monsters and a bit too much exposition in the opening pages, but since Amazon doesn't allow half stars, I'm rounding it back to 5 stars to reflect the originality of the story and the strength of the writing and art. I'm hooked and eager to see the next installment.
