I can’t find a reference online yet, but BBC TV is reporting Vladimir Nabokov’s last novel has been revealed. Titled Laura, it was kept in a vault since his death, and his family is just now bringing it out. Not sure, but from what I heard it sounds like it may be similar to Lolita.
Seems to have been a Franz Kafka situation. When he was about to die, Nabokov asked his family to burn it, but they could not bring themselves to do so.
