This story by Jessica Soffer from Granta last year, called "Beginning, End," seems to me to be a better and more pleasingly economical take on the same conceit at Jonathan Safran Foer's recent New Yorker story, "Here We Aren't, So Quickly." (Fun fact! Jessica Soffer recently received her MFA from Hunter, where Foer's spouse, Nicole Krauss, is an instructor. So maybe they both learned from the best!)
