It's not only the story of a huge scientific achievement. I found it to be the very interesting story of a scientist's career.
Here's the publisher's description for the book A Life Decoded: My Genome - My Life, by J. Craig Venter:
The triumphant memoir of the man behind one of the greatest feats in scientific history
Of all the scientific achievements of the past century, perhaps none can match the deciphering of the human genetic code, both for its technical brilliance and for its implications for our future. In A Life Decoded, J. Craig Venter traces his rise from an uninspired student to one of the most fascinating and controversial figures in science today. Here, Venter relates the unparalleled drama of the quest to decode the human genome—a goal he predicted he could achieve years earlier and more cheaply than the government-sponsored Human Genome Project, and one that he fulfilled in 2001. A thrilling story of detection, A Life Decoded is also a revealing, and often troubling, look at how science is practiced today.
