Almost Transparent Blue

Narrated by the main character Ryū, the novel focuses on his small group of young friends in the mid-1970s. Living in a Japanese town with an American air force base, their lives revolve around sex, drugs and rock 'n roll.

The near-plotless story weaves a vividly raw, image-intensive journey through the daily monotony of drug-induced hallucinations, vicious acts of violence, overdoses, suicide, and group sex.
