When Hannah inherits an apartment in Paris that has been shut up since World War II, she doesn't know what to think.  The more she uncovers in the apartment, the more she learns about her family's past.  At the end of every chapter, there is a diary entry from Hannah's great-grandmother.  Ivy's diary reveals what it was like to live in Paris during the 1920s and 1930s.

Lost in Paris is the perfect daydream, discovering an apartment that has been left to you and hasn't been touched in decades.  While I was surprised that the apartment didn't factor more into Ivy's story, Hannah's discovery of it and uncovering more of her own story made for an entertaining read.
