Historical Fiction

I went through this phase in 4^th and 5^th grade.  I haven't reread them since so cannot say how they translate to an older reader.  I say go for it regardless.  

The Orphan Train Quartet, Land of Hope trilogy, High Trail to Danger and sequels- all by Joan Lowery Nixon- this and Rinaldi describes 4^th grade (which I would place as the minimum level for readers).

Hang a Thousand Trees with Ribbons and almost anything else by Ann Rinaldi (though this one is my absolute favorite)- again, 4^th grade and the way I learned history.  Depending upon age, some may need discussion.
