Query: A GREAT IMPROVISATION is a Great Treat

The brilliantly insightful Stacy Schiff proves yet again that she is, without a doubt, one of America's most gifted biographers. Benjamin Franklin springs to life here in all his complexity: Schiff's elegant prose renders his seven-year stay in France utterly fascinating. The nuanced portrait of Franklin that emerges in these pages will be of great interest to anyone at all intrigued by this endlessly complicated figure and his role in American history. I would venture to say that A GREAT IMPROVISATION is as compelling as the very best novels--the sort that once you've begun, you simply can't put down. And this, I believe, is in no small part due to Schiff's prose, which is as lucid as it is graceful--qualities much sought-after but not often found by discriminating readers. One would expect nothing less from this Pulitzer Prize-winning author.
