Although it seems on it surface like a simple story Bone has a great many layers and in "Rock Jaw: Master of the Eastern Border" we find another. There appear to be two sides to the main plot of this story, the first being that of the dragons along with Rose, Thorn and the bones, and the other is the Lord of the Locusts along with the rat creatures. Rock Jaw is the first character we see that has no real allegiance to either side, he simply wants to rule his small part of the world.
Fone Bone and Smiley Bone meet Rock Jaw as they are traveling into the mountains to free a child Rat Creature that they have rescued and taken care of. While there they find many orphaned creatures whose parents have been eaten by the Rat Creatures. This brings together the idea of eating in a fantasy world such as Bone where the animals are able to speak and all seem as intelligent as humans. Does being a carnivore become immoral if the only creatures available to eat are intelligent?
In addition to dealing with Rock Jaw, Fone Bone and Smiley Bone also are forced to deal with Kingdoc leader of the rat creatures who has decided to deal with the bones himself.
This is the first of the Bone books with a single plot line as well as the first that had no human characters and yet there was no significant tone change. The plot still moved forward at the same relaxed pace slowly revealing more about all of the characters as we went along as well as keeping a considerable amount of humor going.
Although this is the fifth book in the Bone Series that has had a remarkably consistent art style with no humans this feels a little more like a cartoon book making the moments when they discover a truly realistic looking temple even more striking.
Bone is a very unique book with a feeling that can not quite be compared to anything else directly. Parts of it have almost the tone of a Saturday morning cartoon while others are deadly serious and all of it together makes for something that never feels like it is a truly important story yet draws you along making you need to see the next book to find out what is going to happen, so if you're interested in comics that are smart, funny and don't have grown men in spandex punching each other consider Bone.
