Victoria Bedford, University of Indianapolis:
Given the book's academic strength, it is unusually engaging in its content. The writing is excellent. The breadth of relevant topics is superlative. And it makes a clear case for the importance of clinicians understanding sibling relationships.

Karen Gail Lewis, coeditor, Siblings in Therapy:
An exciting presentation of the authors' study of middle and late adulthood relationships. It debunks generalizations that lob siblings into a static category, such as birth order. The brothers and sisters in this study demonstrate that this significant relationship is not static. Covering frequently overlooked topics such as parental interference in adult siblings' lives, emergency health crises, and sibling cut-offs, as well as extensive case studies, this is an excellent resource book for clinicians and for brothers and sisters.

Scott A. Myers, West Virginia University:
Combining classic family therapy theories with both current research findings and contemporary case studies, Geoffrey Greif and Michael Woolley provide readers with an insightful yet fascinating glimpse into how middle-aged adults negotiate their sibling relationships. This book is a must-read for family researchers and therapists interested in learning how affection, ambivalence, and ambiguity work together to frame how adult siblings view their relationships.

Avidan Milevsky, Kutsztown University, author of Sibling Relationships in Childhood and Adolescence:
Although several recent books have been written on siblings, the majority of them are not based on a serious review of the scientific literature or on an empirical study. This is why a research-based book like this on siblings is so timely.
