Lynda Leal Prince teaches high school social studies, runs marathons and ultra-marathons, has studied five languages but mastered none, kayaked 600 miles of the Yukon River, survived the winter of ‘88-‘89 in Fairbanks, didn’t flunk out of Harvard, fought off an attacker with her bare hands, helped deliver a baby in a country where she didn’t even know the word for ‘soap’ in the local language, is a sugar addict who gave up sugar for 6 weeks straight last winter, and saved the princess once. Parenting, though, remains the hardest thing she’s ever done.
