Agree that 3 is great. My favorite is 1, which is next-level even by the high Caro standard: moving to the hill country? Finding un-censored copies of LBJ's yearbook? Unearthing his affair with Alice Glass and the tales of family conflict from his brother? The manic ambition of his first Congressional race as related by his driver? The secret, crucial influence of Brown&Root? -- WTF, no other writer in a thousand years could have written that book. Also, I'll put in a plug for 2, which in my opinion is sorely underrated.
