奥巴马出生于夏威夷。父亲是肯尼亚一名黑人经济学家，母亲是美国一名白人女教师。父母在奥巴马两岁的时候分手，在听说父亲1982年在肯尼亚死于车祸前，奥巴马只见过父亲一次，奥巴马跟着母亲和姥姥姥爷长大。

父亲离开了，奥巴马跟着母亲长大。邓纳姆后来嫁给了一名印尼石油公司的经理罗罗·素托罗，素托罗由于工作的关系需要去雅加达，于是，邓纳姆带着6岁的奥巴马去了印尼。奥巴马在印尼度过了四年的童年时光。

10岁时，母亲与继父离婚，奥巴马回到了夏威夷，大部分的时间他和外祖父外祖母生活在一起。

在2004年7月，民主党召开全国代表大会，奥巴马被指定在第二天做“基调演讲”。所谓“基调演讲”，就是民主党人阐述本党的纲领和政策宣言，通常由本党极有前途的政治新星来发表，1988年做“基调演讲”的人就是时任阿肯色州州长的克林顿。奥巴马不负众望，他亲自撰写演讲稿，并发表了慷慨激昂的演说。在演说中他提出消除党派分歧和种族分歧、实现“一个美国”的梦想。

45岁的奥巴马演说极具魅力，灿烂的笑容更虏获许多民众的心。与过去有意竞选总统的黑人前辈相比，奥巴马是首位在初选前民调获得全国性支持的明日之星，打败2008年成为美国历史上首位黑人总统。

In this lyrical, unsentimental, and compelling memoir, the son of a black African father and a white American mother searches for a workable meaning to his life as a black American. It begins in New York, where Barack Obama learns that his father—a figure he knows more as a myth than as a man—has been killed in a car accident. This sudden death inspires an emotional odyssey—first to a small town in Kansas, from which he retraces the migration of his mother’s family to Hawaii, and then to Kenya, where he meets the African side of his family, confronts the bitter truth of his father’s life, and at last reconciles his divided inheritance.
