Okay, so 'Moonrise' is a bit ambiguous—could be Sarah Crossan's verse novel or maybe something else? But if we're talking the one by Sarah Crossan, the key characters are pretty much centered on Joe. He's the protagonist, a teenager reconnecting with his older brother Ed who's on death row. Their relationship is the absolute heart of the story.
Ed himself is a massively complex figure. You only really know him through Joe's memories and their visits in prison, which makes his character this haunting, fragmented presence. Then there's Joe's sister, Angela, I think? She's trying to hold the family together. Their absent mom is a ghost in the background too, shaping everything.
It's less a huge cast and more this intense, close-up look at a family shattered by the system. The warden and a few others pop in, but honestly, it's Joe and Ed's bond that you remember. The way Crossan writes it in verse makes every interaction feel raw and immediate.
I read it in one sitting and just felt drained afterward, in a good way.
