In this bold and insightful book, Julie Anne Peters tells a dual story of transition, identity, and love. Regan is a high-school girl dealing with all of the pressures of being a teenager, but she is also privy to the most secret piece of information: at night, her brother Liam transforms into Luna. Liam has an equally difficult problem -- he is a woman stuck in a man's body. As the siblings struggle with their identities, secrets, relationships, and troubles, they grow to understand themselves and each other better. A powerful and touching book -- I read it in one sitting! –Karen H.-
