I am a huge fan of the Lunar Chronicles. This is a great backstory to Alice in Wonderland’s Queen of Hearts. If you’ve read the others then you will love this one. Even though it is a 2.5 book in the series, it is not necessary to read to enjoy the regular series. Although I normally dislike it when authors go back and write books that occur mid-series, this one does well as it is it’s own story and does not effect the regular story. Pick it up and read it.
