"...In the brutal prison camps of the Union Army Dr. Samuel Knight healed his fellow captives who'd given up hope. But now with the war over and the South in ruins the good doctor faces his hardest challenge yet. Penniless and hungry Knight has to beg borrow and steal to survive. By the time he reaches his home in East Texas it's been taken over by a Yankee carpetbagger--and the jacksl has forced Knight's wife to marry him. Now Dr. Knight is going to take back what belongs to him."--Provided by the publisher.
