In the Face of Death — Chelsea Quinn Yarbro

Madeline de Montalia, the perpetually youthful and beautiful vampire, once beloved of the Count Saint-Germain, comes to America in the 1840's to live with and study the native tribes of America, desiring to document their culture and knowledge before these are changed forever and unalterably by contact with the White Man. She had not expected she would fall in love with San Francisco Banker and US Army officer William Tecumseh Sherman in the 1850's. Now, living among the Choctaw in Georgia in the 1860's, she knows that Sherman's armies are marching through; and what will she say when they meet again after these many years? And how will she survive through some of the most horrifying events of the Civil War?
