The second edition of The Selective Mutism Resource Manual is without doubt the most comprehensive, knowledgeable and most importantly useful manual on the nature and treatment of Selective Mutism (SM) available at the time of writing this review (Jan 2017). With decades of effective clinical experience of SM between them, the authors have such a level of understanding that important advice is found within the text on every page [..] Selective mutism is a very distressing and disabling anxiety disorder. This manual should give all those who encounter it, be it as a family member, friend, school teacher, practitioner, sufferer or in any other walk of life, the tools they need to help reduce the enormous impact it can have on people's lives. - Shirley Landrock-White, SMIRA
