End of the world house : a novel
(Book)

"Bertie and Kate have been best friends since high school. Bertie is a semi-failed cartoonist, working for a prominent Silicon Valley tech firm. Her job depresses her, but not as much as the fact that Kate has recently decided to move from San Francisco to Los Angeles. When Bertie’s attempts to make Kate stay fail, she suggests the next-best thing: a trip to Paris that will hopefully distract the duo from their upcoming separation. The vacation is also a sort of last hurrah, coming during a ceasefire in a series of escalating world conflicts. When a mysterious stranger offers them a private tour of the Louvre, the women find themselves alone in the museum where nothing is quite as it seems. Caught up in a day that keeps repeating itself, the two are eventually separated, and Bertie is faced with a mystery that threatens to derail everything." --publisher's website
