From the author of the internationally acclaimed, award-winning The Harmony Silk Factory comes an enthralling new novel that evokes an exotic yet turbulent and often frightening time and place. Map of the Invisible World is the masterly, psychologically rich tale of three lives indelibly marked by the past—their own and Indonesia's.    Sixteen-year-old Adam is an orphan three times over. He and his brother, Johan, were abandoned by their mother as children; then Adam watched as Johan was adopted and taken away by a wealthy couple; and now Adam is hiding because Karl, the man who raised him—and who is Dutch but long ago turned his back on the country of his ancestors—has been arrested by soldiers during Sukarno's drive to purge 1960s Indonesia of its colonial past.    All Adam has to guide him in his quest to find Karl are some old photos and letters, which send him to the colorful, dangerous capital, Jakarta, and to Margaret, an American whose own past is bound up with Karl's. Soon both have embarked on journeys of discovery that seem destined to turn tragic.    Woven hauntingly into this page-turning story is the voice of Johan, who is living a seemingly carefree, privileged life in Malaysia, but one that is careening out of control as he struggles to forget his long-ago betrayal of his helpless, trusting brother.    Map of the Invisible World confirms Tash Aw as one of the most exciting young voices on the international literary scene.
