This was an amazingly, beautiful novel. I loved everything; writing, characters, story. It was a sad moment when I reached the last page. I suppose that would be why Anthony Doerr won the Pulitzer Prize. 
The writing style is poetic with short chapters switching perspectives between the two main characters, Marie-Laure and Werner. It's a very sensory story relying on sight and sound. This is a book that you will want to take your time with as the writing is lovely. Otherwise, the story itself is fast paced with moments of suspense. 
This is a book that I will be recommending and one that I would enjoy rereading.
