Mississippi Raiders

She came out of the Louisiana bayou, a hard-riding young beauty who had seen her parents killed in cold blood by agents from the North. Driven by her desire for revenge, Belle joined the Great Cause. That took her into the heart of a nation cleaved in two, and closer to her parents' killers. Joining the Secret Service of the Confederacy, she pitted her courage, wits and fighting skills against the Union's best agents. But while she spawned a legend with her daring escapades and undercover work, her greatest challenge still lay ahead, on a mission deep behind enemy lines – to stop a deadly new weapon from entering the war!
