Coal Black Horse - Robert Olmstead

When Robey Childs's mother has a premonition about her husband, a soldier fighting in the Civil War, she does the unthinkable: she sends her only child to find his father on the battlefield and bring him home.

At fourteen, wearing the coat his mother sewed to ensure his safety-blue on one side, gray on the other- Robey thinks he's off on a great adventure. But not far from home, his horse falters and he realizes the enormity of his task. It takes the gift of a powerful and noble coal black horse to show him how to undertake the most important journey of his life: with boldness, bravery, and self-posession.

Coal Black Horse joins the pantheon of great war novels-All Quiet on the Western Front, The Red Badge of Courage, The Naked and the Dead.
