Over the course of a half-century, Vladimir Nabokov wrote hundreds of letters to his wife Vera, which are being published in book form this week for the first time. Among other things, they reveal the absurd pet names he invented for her (such as Goosykins and Monkeykins) and display Nabokov musing over whether or not to borrow a friend’s castle for the summer. Also worth reading: our own Garth Risk Hallberg on Nabokov’s Ada, or Ardor.
