Who is the narrator, can she or he read minds, and, more importantly, can we trust her or him?
First Person (Central Narrator)
It's interesting that though the story is called Luna, it actually isn't told from Luna's perspective—nope, we're firmly planted inside Regan's head for this tale. By removing the narrator by one step, the book allows us to see Luna's struggles and family life intimately, but also to see how the world views Luna from an outside perspective. Pretty clever maneuver, right?
Regan is the perfect character to guide us through the book because she is definitely in the thick of the action. As Luna's sibling, Regan shows us both what goes on at home and what happens to Luna when she goes to school. And in the process, we understand not only that being trans* is hard for Luna to navigate, but also for Regan.
Regan is Luna's closest confidante, so she hears about all her feelings and talks her through her depression and despair over transitioning. This closeness makes the point of view extremely personal, while also showing us the pain that Regan feels for herself and for Luna. For instance, when Luna is picked on at the mall, Regan feels her sibling's pain acutely:
She unlatched her purse with a shaky hand and dropped the key into my palm. Any second now she was going to disintegrate, implode, disembody. "Oh God. Luna." I squeezed her hand. "I'm sorry." What else could I say? What could anyone say? (11.101)
When things get tough, we get to see all of it from Regan's very own perspective. Fortunately for Luna, her sister really loves her… otherwise, this would be a very different book.
