Theodore Roosevelt--A Life by Nathan Miller.
Like all politicians, TR was a complicated man, and although a Republican, was certainly not a small-government conservative Republican. Some things he did I like, some things, no so much, but he definitely lived life on his own terms.
For further reading about TR try The River of Doubt: Theodore Roosevelt's Darkest Journey, by Candice Millard. The former President goes on an insane journey up an uncharted tributary of the Amazon. They're attacked by Indians, lose supplies and canoes in the rapids, there's a drowning, a murder in the ranks, three men die, they face starvation, disease, and TR is brought back from the brink of suicide.
I've always been fascinated by that war. I'm adding this to my reading list. Edit: Grammar.
Two books I'd recommend: The War of Atonement, The Inside Story of the Yom Kippur War, by Chaim Herzog...and Michael B. Oren's Six Days of War: June 1967 and the Making of the Modern Middle East.
Both wars are worthy of study and many of the same principle characters had major roles in both conflicts.
