Whether loving or fraught, competitive or codependent, these bonds shape us in lasting ways. In this heartfelt, judgment-free book, Catherine Carr invites us to look at our brothers and sisters beyond the labels assigned in childhood. Combining real-life stories with expert insight, she explores birth-order stereotypes, favouritism, trauma, blended families, only children, siblings with additional needs, and the pain of estrangement and bereavement. Thinking about these relationships more deeply may help us better understand ourselves and the world around us. *Interwoven with candid interviews with sibling pairs taken from her hit podcast, Relatively, such as Chris and Xand van Tulleken, Johnny and Lillie Flynn, Nick and Gill Hornby, Manni and Reuben Coe, and more*
