"DDP has rightly established itself as a hugely influential therapeutic model for working with trauma. Pioneered by Dan Hughes' inimitable trailblazing ability to synthesize rich longstanding clinical expertise with the latest developmental science, this excellent book beautifully illustrates DDP in action. It successfully interweaves fine-grained case examples with neurobiology, attachment and trauma theory, alongside careful explanations, leaving the reader in no doubt about the effectiveness of this model, and equally importantly, explaining exactly why it works so well. This book is a credit to the authors and the field, and practitioners from the most experienced to those brand new to DDP or trauma work will find huge benefit in it.".
