The author of Paris to the Moon, Adam Gopnik, has published another collection of essays. Beginning with his return to his beloved New York City, Through the Children's Gate covers everything from the lyrical, trying to figure out how to get the Darling children to fly in his son's school's production of Peter Pan, through to the painful task of explaining the 9/11 attack on the World Trade Centre to his children.
