Throughout the years, Regan has always been there to support her transgender brother, Liam, or Luna. But when she decides that she wants to make the transition to a female permanent, Regan isn't sure that she is able to handle the consequences. When her new chemistry lab partner takes an interest in her, Regan just wishes that her brother could be normal, that his conflict would just go away. But in order to do that, Liam/Luna needs to learn to free her true self, for only then can Regan truly be free.

In young adult literature, there aren't many novels about transgender youth, which makes this novel especially unique. Despite the fact that the number of LGBTQ novels in general has been rising, novels about transgender teens still have surprising low numbers. I think that was one of the main reasons that I liked this book. Even though the transgender teen wasn't the main character (if you're look for one of those, check out I am J by Cris Beam), Luna is a big step for the transgender community. Readers get a look into the lifestyle of a transgender person, and while it doesn't necessarily help them to see how transgender people think, it does show what their lives are like, the things they struggle with, and the kinds of things their family might go through. The main character, Regan, is also a relatable character because of how she goes through school, and interacts with her brother. Those who have siblings will be able to relate with how she feels about Liam/Luna sometimes, even though their own siblings may not be transgender. Overall, I think this is a beautifully written book that speaks volumes about the transgender lifestyle. I only hope that soon, more books like this, and maybe even books improving on this, can be published.

As for a classroom, this might be a tricky book just because it deals with transgenderism, and a lot of parents might not be comfortable with that topic. However, this is an important book to use in classrooms because of this fact. Not many people know a lot about transgender people, and Luna could definitely be used to show students that transgender people aren't all that different from them. This book could be used to promote acceptance, as with any LGBTQ book.
