Her essay is about Gloria Whelan's book, After the Train. In it, Rebecca hones in on the play-Indian theme in the book.
Barbara Bietz, in her review in the Association of Jewish Libraries Newsletter didn't note the play-Indian theme at all. Hazel Rochman's review in Booklist doesn't mention it. Neither does independent reviewer Carol Ann Lloyd-Stanger, or the unsigned Kirkus reviewer, or Hope Morrison of The Bulletin of the Center for Children's Books.
On page 108, Whelan writes:
We pool our money and buy a copy of a Western by Karl May, Winnetou, the Apache Knight. Karl May has written all these great books about the American West, and the amazing thing is he's never been there! You have to wonder how he can make it all seem real.
I wonder why all those other reviewers did not mention the Karl May book? Did they not see it? Did it not matter?
Thanks, Rebecca, for your essay and the link.
