Query: Heart piercing and beautiful

What a beautiful book. I didn't engage till half way through -- the story's early pace is slow and meandering. But half way through: look out. Your heart will be struck by lightning. The quiet tone of the book is shattered by the events of one very snowy winter. I'm a teacher reviewing the book for my at-risk 5th graders. They would have too much difficulty with the vocabulary, but if I read it to them, they may be able to appreciate this small, rich slice of culture in the mid-19th century
