Know Nothing: Book III of the Beulah Quintet

For some reason, my local library had all but this novel in Settle's excellent series. I've read The Beulah Quintet twice now and find the books rich and well written.

Novel set just before the Civil War and tells the tragic tale of Peregrine Catlett and his second son, Johnny. As Peregrine considers freeing his slaves, he realizes all his children have left, and he feels there's no recourse but to remain a slaveholder. Tied by a special bond to the land, Johnny returns, but only until the outbreak of war, when he joins the Confederate forces. But he loses sight of his reasons for joining the war...and ends up fighting both family and friends with disastrous results.
