'A perfect balance of theory and lived experience, this book is a great starting point for those seeking a better understanding about autism. Although it is primarily discussing autistic adults, I think it is a valuable book for those teaching autistic children, to read. All of our children eventually turn into adults - it is so important for those in education to listen to autistic adult's experiences so we can better support the new generation.' - Lucy Brookes'This book covers a broad range of topics which have been brought to life through the unique collaboration of autistic people. It gives the reader excellent practical resources to support autistic adults. Its chapter on mental health and identifying the similarities and differences is particularly useful in addition to the book highlighting the shortfalls of current assessment tools and the need of a clinician to use their clinical judgement. This is a really useful, well thought out book which provides an overview of number of topics with useful information and guidance but also highlights the positives of autism.' - Dr Sonia Anderson, Clinical Lead for Autism Service
