Book about girl on the prairie?
About 10 years ago I read this book about a girl who is living at home with her parents and a gypsy stops by asking for money, and her parents won't let her give the gypsy any. Then the gypsy curses her or says that she'll have an unfortunate bloodline or something like that, and then something happens to her parents, and she ends up being adopted by a family on the prairie. And all the details about that are hazy, except for their their dog getting bit by a rattlesnake.
