Query: To set you straight....

The long review referring to the Mask of Many Colored Crow is not actually about People of the River. It's about People of the Lakes, my favorite book. However, People of the River is extremely excellent as well. This story especially touched me, a young reader, because of its heroine Lichen, who is only ten. I was twelve when I first read this book. It DOES contain mature subject matter probably unsuitable for kids, but if you appreciate excellent writing, you have to read this
