Hudson is a skilled reader of books, but not so much with people. Mum’s new bloke Louis is keen to help, and in turn Hudson passes on what he learns to future sibling Zed (for zygote). This all comes in useful at granddad’s funeral as Hudson deals with grief, his dad’s feelings of guilt and his own sadness about his parents’ separation. Hudson’s self-awareness about his Asperger’s and how it affects him (and others) gives him a distinctive and insightful voice that offers an astute and ultimately uplifting take on the world.
