Best books about Franklin Delano Roosevelt?

[HeilHeiser]

I'm a WWII buff (and Civil War, Rome), and I was thinking how little I still know about Roosevelt. Despite the length and importance of his presidency, he still is a shadowy character to me. I was wondering what the best books are about him. I'm particularly looking for in-depth looks at his presidency during WWII, but wouldn't mind books including the New Deal as well as a decent summary of his personal life. Thanks.

For FDR in general, start with Schlesinger. For more WWII-specific material, James MacGregor Burns or Robert Dallek.
