The concluding book of the Don Tillman Trilogy finds Don, Rosie and their 11-year old son Hudson relocating to Melbourne. Hudson’s school observes some social troubles and requests an autism assessment. This stimulates Don’s formidable problem-solving abilities, the Hudson Project, to aid Hudson in acquiring skills to fit in. The story addresses important questions: is labelling useful in terms of identity; should people on the autism spectrum adjust their behaviour and thinking to match neuro-typical norms? And there is bullying and a confrontation with an anti-vaxxer parent. Overall, a compelling read, with humour and psychological insight into the complexity of human behaviour. Highly recommended.
