Heijder has taken a completely new and 21st-century approach to the study of the 19th-century genius Beethoven. The book is exciting, convincing and well-founded. We regard this text as an asset that not only conveys the drawbacks associated with Asperger syndrome, but demonstrates its positive aspects, as well.
