The surgeon-as-rock-star mystique seems like it must have come straight out of Hollywood, but the myth had to begin more concretely. A good candidate is Minnesota's Dr. Walt Lillehei, the hard-working, hard-playing father of open-heart surgery, whose life is told in garish color in King of Hearts by journalist G. Wayne Miller. From his early brilliance, recovery from deadly lymphatic cancer, and dramatic repair of seemingly hopeless heart cases to the disintegration of his career at its peak thanks to an army of personal enemies and conviction on tax evasion counts, his story is consistently surprising and engaging. Fast cars, hard drinking, and plenty of women filled his time when he wasn't turning lives around with a few strokes of his scalpel, and the reader will find the surgeon's actions almost unbelievable--rarely endearing, but occasionally saintly. Combining this melodramatic biography with the fascinating story of the struggle for open-heart surgery, considered impossible little more than a generation ago, Miller makes a compelling case that the daring scientist was simply another side of the arrogant, absent-minded playboy. No ordinary biography, King of Hearts is breathless reading--you'll find yourself surfacing every few chapters to remind yourself its nonfiction. --Rob Lightner
