A book of rare beauty: "Ru" is a lullaby of Vietnam and a love letter to a new homeland. Ru: In Vietnamese it means lullaby; in French it is a small stream, but also signifies a flow - of tears, blood, and money. Kim Thuy's "Ru" is literature at its most crystalline: the flow of a life on the tides of unrest and on to more peaceful waters. In vignettes of exquisite clarity, sharp observation and sly wit, we are carried along on an unforgettable journey from a palatial residence in Saigon to a crowded and muddy Malaysian refugee camp, and onward to a new life in Quebec. There, the young girl feels the embrace of a new community, and revels in the chance to be part of the American Dream. As an adult, the waters become rough again: now a mother of two, she must learn to shape her love around the younger boy's autism.
