In the first full-scale life of the most important composer-lyricist at work in musical theatre today, Meryle Secrest draws on her extended conversations with Stephen Sondheim as well as on her interviews with his friends, family, collaborators, and lovers to bring us not only the artist - as a master of modernist compositional style - but also the private man.

We see Sondheim at work with composers, producers, directors, co-writers, actors, the greats of his time and ours, among them Leonard Bernstein, Ethel Merman, Richard Rodgers, Oscar Hammerstein, Jerome Robbins, Zero Mostel, Bernadette Peters, and Lee Remick (with whom it was said he was in love, and she with him), as Secrest vividly re-creates the energy, the passion, the despair, the excitement, the genius, that went into the making of show after Sondheim show.
