Belle Boy: A Sister in the Rebel Ranks

Midwest Book Review says Belle Boy is "both educational and entertaining read throughout for secondary readers"!

When Samantha Anne's brother, Johnny, goes missing-in-action while fighting for the Confederate army, she takes on the responsibility of finding him herself. Lucky for her, she grew up tagging along with Johnny and his friends, doing things a proper Southern Belle should never do. These skills come in handy as she disguises herself to join the rebel ranks.
Between fierce and bloody battles, she searches the tired, filthy faces of soldiers looking for Johnny. Along the way, her life is forever changed by the difficult choices she is forced to make, the horrors of war she shares with her fellow soldiers, and the courage she discovers within.
