Both Dr. Fleming and Dr. Wilson recommend Felicity Allen's biography of Jefferson Davis (Google Books). Dr. Wilson also writes:
Should you want to go further, there is Hudson Strode’s biography and the memoir by Varina Howell (Mrs. Jefferson) Davis. Other treatments are not entirely bad but less satisfactory. I challenge anyone to read our President’s farewell to the Senate in 1861 and his first and second inaugural addreses, lay them beside Lincoln’s duplicitous folderol, and not see who was the better man.
His first inaugural address. Second inaugural address. Farewell to the U.S. Senate, January 21, 1861.
