"Bertie and Kate have been best friends since high school... [Bertie's] job depresses her, but not as much as the fact that Kate has recently decided to move... When Bertie's attempts to make Kate stay fail, she suggests the next-best thing: a trip to Paris... One night in Paris, they meet a strange man in a bar who 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, Bertie and Kate are eventually separated, and Bertie is faced with a mystery that threatens to derail everything"-- Provided by publisher.
