Sometimes Madness is Wisdom -- Zelda and F. Scott Fitzgerald: A Marriage, by Kendall Taylor. Ballantine. 416 pages. $28.
It's a tale at once fascinating, compulsively readable and unbearably sad. The story of Zelda and F. Scott Fitzgerald -- the golden young couple who embodied all that was beautiful and damned about the Jazz Age -- has been told repeatedly over the years. But in Sometimes Madness is Wisdom, Kendall Taylor takes a lifelong interest in the doomed Zelda and molds it into a book that is wise, compassionate and distinctly different.
