Change is the one thing every autistic adult learns to dread and to navigate in equal measure. A cancelled train, a shifted work rota, a surprise visitor — each one can feel like the ground tilting. Yet the assumption that autistic people cannot handle change does a deep disservice to the many of us who, with the right strategies, adapt in ways that surprise even ourselves. This book is not a manual to cure an aversion to disruption. It is a companion for understanding why routine matters so deeply to an autistic brain, how to rebuild quickly when the familiar vanishes, and how to distinguish between healthy predictability and rigidity that holds you back. Drawing on the shared experience of late-diagnosed adults, each chapter offers a way to map your own relationship with change — from small daily shifts to life transitions — without being told to simply 'try harder'. You will find no checklists pretending to be a diagnosis, and no promises that adaptation is effortless. What you will find is permission to take change at your own pace, with language that respects the brain you have always had. Part of The Late Diagnosis Library.
