The first thing that struck me about Sarah's Key was how beautifully the words flowed. The second was how contrived many of the characters felt. Perhaps due to this second revelation, I did not follow the same emotional journey as the protagonist of this story (although I appreciate the author's attempt to bring me along). The novel deserves a mature audience; as a 22 year old, I lost interest around half way through the book.
All in all, Sarah's Key is a good read, but not great.
