Hello. I have added a link below that will give you a portion of Donald Barthelme's second novel, Snow White. I'm sorry that the entire text is not included, but I don't think it is available on-line at any site. You can also get added information from the eNotes links below.
I'm sure you will find Barthelme's version of the Grimms' Brothers' classic a bit different. Snow White has long black hair, is an unhappy "horsewife," and apparently has more than just friendly relations with the seven guys who live with her. It is certainly an unusual modern approach to the classic fairy tale.
