This seems to be a very similar book to Medicine River. Similar characters, similar setting, similar everything... It's ok, but I am not sure I want to stick with this one.
Neither Medicine River nor this one seem to have the magic and pull that The Back of the Turtle had.
I also have King's Green Grass, Running Water on Mt. TBR, which seems to also be set in Medicine River and I might just sample that one before deciding whether to read it or pass.
