The story of the Roosevelts is usually seen as a tale of two presidents—Theodore and Franklin—separated by time and politics, and of two families—the Oyster Bay and Hyde Park branches—that had little to do with each other. Collier and Horowitz paint an explosive new portrait which offers a completely unique view of America's longest lasting and most powerful dynasty.

In this brilliant biography, we see for the first time how the family divided into two branches and began an epic battle for the family legacy. We see for the first time how the ideals of two presidents were passed on to members of later generations, ennobling some and crushing others. The Roosevelts is a rare look at what brought this exceptional group of people together and what drove them apart.
