Making sense of the longest relationship of our lives

For most of us, our sibling relationships are the longest we will ever have. 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.

These relationships are rarely straightforward but thinking about them more deeply may help us better understand ourselves and the world around us.
