There is a wise argument out there that Zadie Smith, better known for some of the finest novels of this young century, is actually masquerading, that she's really been one of our finest essayists the whole time. This collection of autobiography, criticism and rangy impressions already feels like a quiet classic, a phone book of thoughts on everything from joy to childhood bathrooms to Brexit to movies — her essay on "Get Out" is undoubtedly the smartest thing written about that very written-about film. Her piece on Facebook — "500 million sentient people entrapped in the recent careless thoughts of a Harvard sophomore" — is worth the price alone. But the rest is accessible without feeling tied to convention, that rarest and most necessary of works, the portrait of an artist dizzy with curiosity and insight.
