This book is an absolutely must-read for anyone who is TS, or even just questioning or curious about transsexuality. It is a touching and emotional story that breaks free of conventional boundaries, about a teenaged MtF going through transitioning, told from the viewpoint of her sister. I was nearly brought to tears the first time I read it, and I guess it also helped me in the discovery of my true self, though I was already expressing her on the Gaia forums, I wasn't completely aware of what she was until I read this book. This book, along with other books by the same author, such as "Keeping You a Secret" and "Define 'Normal,'" have quickly climbed up my personal favorite books list to reside in the top slots, along with books from my earlier years, like "Ender's Game" by Orson Scott Card "Killobyte" by Piers Anthony, and the Chronicles of Narnia series by C. S. Lewis. But what I thought was truly awesome about Julie Anne Peters was, when I flipped "Luna" over for the first time, and read the back cover, I found out that she lives right here in Colorado, in the city of Lakewood, which isn't that far from where I live.
