When two American sisters travel north from Ho Chi Minh City to Hanoi, conversations with Vietnamese strangers and friends reveal to them the flip side of a shared history. Lynne and Dana Sachs’ travel diary of their trip to Vietnam is a collection of tourism, city life, culture clash, and historic inquiry that’s put together with the warmth of a quilt. Which Way Is East starts as a road trip and flowers into a political discourse. It combines Vietnamese parables, history and memories of the people the sisters met, and their own childhood memories of the war they witnessed on TV.
