The book "Fairest" by Marissa Meyer is actually a prequel to "The Lunar Chronicles," but (to me) is meant to be read AFTER reading the main four books. This book is all about Queen Levana, the main antagonist of "The Lunar Chronicles." The story shows the reader all the reasons why she is the way she is, and shows us the events that happened to start the series. "Fairest" is about The Evil Queen, who brought the most grief to the "princesses" of the first four books.
Overall, the book is a very good read after reading the main four books. Reading the book before may be confusing. The characterization of Queen Levana is truly amazing, as more often than not, antagonists are not given enough character, and are not explained well. Some aspects of the story are predictable if you have already read the series, but not all scenes are. This book answers many questions about Queen Levana, and is definitely worth the read.
*Do note that "Fairest" was published before "Winter" and that you can read all of the side books in whatever order you like.
