As they travel from cage to bars to glass, over all the fake landscapes of the zoo, Jonah wonders about his mum and dad, what they've done and haven't for him, and what he has and hasn't done in return. He realises, as he goes, the complexities of growing up. The Zoo, A Going employs beautiful language without sacrificing plot or characterisation, and how the small act of a family visiting the zoo becomes a life lesson of epic proportions.
