Run Me to Earth by Paul Yoon
Three young Laotians, Alisak, Prany, and Noi, orphaned during the Vietnam War band together and begin working for a doctor named Vang, who runs a field hospital. The trio ride motorcycles on daily trips for the doctor, navigating a countryside dotted with land mines. Vang hopes to save the children, sending them out on the last helicopter evacuating the area. But the rescue fractures the teens' lives as they are split up and sent on diverging paths.
Review from Library Journal:
A National Book Foundation 5 Under 35 honoree, winner of the Young Lions Fiction Award, and author most recently of the LJ best-booked The Mountain, Yoon takes us to 1960s Laos, where three orphans meet fiercely dedicated doctor Vang when they take shelter in a bombed-out field hospital. Soon they are acting as motorcycle couriers, steering carefully across fields laced with unexploded bombs as they help Vang care for the wounded. With a 60,000-copy first printing.
