Book excerpt: This is the first book to consider both deaf and hearing perspectives on the dynamics of adult sibling relationships. Deaf and hearing authors Berkowitz and Jonas conducted interviews with 22 adult siblings, using ASL and spoken English, to access their intimate thoughts. A major feature of the book is its analysis of how isolation impacts deaf-hearing sibling relationships. The book documents the 150 year history of societal attitudes embedded in sibling bonds and identifies how the siblings' lives were affected by the communication choices their parents made. The authors weave information throughout the text to reveal attitudes toward American Sign Language and the various roles deaf and hearing siblings take on as monitors, facilitators, signing-siblings and sibling-interpreters, all of which impact lifelong bonds.
