Heart gear

Roue may be the only human left on an Earth ravaged by powerful weapons, wars, and artificial intelligences called "gears." These gears serve multiple purposes--some of them, like Roue's Uncle Zett, were research gears dedicated to studying the natural order. Others, like the mysterious Chrome, seem to be built for destruction alone. When Roue and Chrome set out on their journey, they originally have a singular goal of restoring their friend, but as time goes on, Roue begins to learn there is more to humanity that these various androids can teach her, and that this world is a very dangerous place for a human. With the number of gears only limited by his imagination, Takaki delves into the philosophical, emotional debate of what comprises a human by speculating how close artificial intelligence can get. The North American release of this book seems perfectly timed with the current increase in demand for and development of AI. Fans of Black Torch will reminisce on Takaki's darker, grittier art style and methodical pacing to character introductions and scenes. Best for older readers because of the prevalence of violence that takes place on the page, as well as some moments of cheeky fan service.
