This would be a lovely 'holiday' read for anyone whether they are knowledgeable about autism or not.
The book does not really have a ending as it is a kind of emotional journey for two persons who do not really understand each other's needs. I feel the book does try a lot to explain the behaviour of Asperger to readers of 14 plus. The language is uncomplicated, with short punchy sentences. It is a very poignant story, the book has been well researched, and it is highly recommended for the emotionally mature reader.
Essinger writes sensitively. Funny, touching and sad, this is a novel which lingers in the memory.
