Hudson is great at understanding books, but people are a different story. His mum’s new partner, Louis, tries to help him navigate life, and Hudson, in turn, shares what he learns with his future sibling, Zed (short for zygote). When granddad passes away, Hudson faces grief, his dad’s guilt, and the pain of his parents’ separation. With a sharp self-awareness of his Asperger’s and its impact on himself and those around him, Hudson’s unique perspective offers a thoughtful and ultimately hopeful view of the world.
