Book excerpt: Troubled by an inability to find any meaning in his life, the 25-year-old narrator of this deceptively simple novel quits university and eventually arrives at his brother's New York apartment. In a bid to discover what life is all about, he writes lists. He becomes obsessed by time and whether it actually matters. He faxes his meteorologist friend. He endlessly bounces a ball against the wall. He befriends a small boy who lives next door. He yearns to get to the bottom of life and how best to live it. Funny, friendly, enigmatic and frequently poignant - superbly naive.
