At first glance, Benjamin Ajak didn't appear to have much in common with his high school audience.
His pinstripe shirt and trousers and red tie were in stark contrast to the laid-back T-shirts and jeans worn by the teenagers.
His crisp English revealed an African accent. Theirs was punctuated by long "O" sounds.
Common ground there was, however, as revealed during Ajak's day-long visit Tuesday to North Lakes Academy in Forest Lake.
The author and former Sudanese refugee paid a special visit to the school, where he played dodgeball with the kids, shared laughs over lunch, and compared notes about American sports and politics.
Ajak, 26, also spoke to students, teachers and the larger Forest Lake community about his experiences as one of the more than 27,000 Sudanese boys orphaned by war.
It was his only stop in Minnesota, as he continues his book tour across the country. Today, he is scheduled to speak at the University of Wisconsin-River Falls.
He and two other "lost boys" joined co-author Judy Bernstein in writing a critically acclaimed book, "They Poured Fire on Us From the Sky," which 10th-graders at the Forest Lake charter school read this year.
