24:5 Blue fingers; by Cheryl Aylward Whitesel

Blue fingers is an interesting book. It's about a pair of identical twins in feudal Japan, where twins are thought to be unlucky. It focuses mainly on Koji, the firstborn of the twins, yet smaller and weaker. His twin, Taro, saves a dye maker from being swept away in a river. Koji is turned in, in a good way, to be the one who saved him. Then he is made apprentice dye maker. It gets really interesting and cool later on, but you'll have to read it yourself.
