Skull water
(Book)

"Growing up outside a US military base in South Korea in the aftermath of the Vietnam War, Insu--the son of a Korean mother and a German father enlisted in the US Army--spends his days with his "half and half" friends skipping school, selling scavenged Western goods on the black market, watching Hollywood movies, and testing the boundaries between childhood and adulthood. When he hears a legend that water collected in a human skull will cure any sickness, he vows to find some in order to heal his ailing Big Uncle, a geomancer who has been exiled by the family to a mountain cave to die. Insu's quest takes him and his friends on a sprawling, wild journey into some of South Korea's darkest corners, opening them up to a world beyond their grasp"--,Provided by publisher.
