Professor Anthony Reid has added this volume on Sumatra, with special attention to Aceh, to his already huge corpus of publications about Indonesia. The book reveals that he remains master of the telling phrase. In this case, the phrase emerges, almost casually, when he tells us that since 1998 the ‘Indonesia project’ has been increasingly challenged. Indonesians might be startled to learn that their country was a project, but Reid presents plenty of evidence here for its incompleteness. Anyone tempted to superficial judgments about the Aceh problem and what it means for Indonesia and the region would do well to read this book.
