Query: Impressive accomplishment

THOMAS JEFFERSON is an impressive accomplishment. Bernstein's masterful grasp of our third president's life and legacy allows him to peel back Jefferson's accomplishments and ambiguities layer by layer, while respecting the essential mystery at the core of his being. Generalists will hail this thorough and concise account of this multifaceted individual. Historians will appreciate Bernstein's meticulous use of source materials, his thorough familiarity with the latest scholarship, and his professional detatchment (unlike so many, this author does not obscure Jefferson with his own agenda, preferring to let his sources speak. As a wordsmith as well as an historian, I particularly relished how this book elicits one of America's gretest writers in language both incisive and elegant.
