Request #373 From Emma

I’ve been trying to find this book (potentially a trilogy?) for a solid 10 years. We read it in grade school- so very early 2000s, but knowing my school it was from at least the 80s. The story is set around the life of a young girl in America during the 1800s. All I can remember is vignettes of the story, which are as follows: 1) at one point, she is with another young girl and the two are dying of hunger. The girl attempts to eat plain, raw flour and becomes extremely ill 2) she is ”kidnapped” by an indigenous tribe and married to one of the boys in the tribe. They grow rather fond of eachother and one night on a hunting trip temperatures drop below freezing so they wrap themselves in a fresh pelt. The pelt freezes them inside, and her husbands feet are exposed. Wolves descend upon him and EAT HIS FEET. i do not remember how she gets out of it but he dies. 3) potentially the same book? But i think there was a scene where she and another kid are sledding and end up falling through the snow/are trapped under an avalanche.
