Bought Clemente 21 to read on a business trip and couldn't put it down. The illustrations are compelling and add a lot to this amazing story. Kids will like it too (8+) but it does deal with racism and some adult themes. It also describes some Christian stories in lovely detail even if your not religious as context for who Roberto was. Don't let the graphic nature of the book fool you, it seems really well researched and is much more in depth than I expected. IMO for the price every fan should own a copy.
