Jonathan Lethem 
As She Climbed Across the Table 

What if your lover left you for nothing? Literally Nothing? From the author of Motherless Brooklyn, this is a strange, hilarious love story about a man, a woman, and the space between them. Physicist Alice Coombs has made a great discovery — a hole in the universe, a true nothingness she and her colleagues call 'Lack'. Professor Philip Engstrand has made his own breakthrough — he realises how much he loves Alice. Trouble is, Lack is a void with a personality — a void that utterly obsesses Philip's beloved. She's fallen out of love with Philip and in love with Lack.
