Star Wars: Poe Dameron issue 1 comes out today from Marvel, while Rey and Finn don’t have prequel comics.
Did I like it? Yes I did.
Likewise in the book Before The Awakening Finn’s story is about the harshness of his training, Rey’s is about the sadness of her lonely life and Poe’s is A Thrilling Space Adventure! This is because Poe starts in medias res in The Force Awakens while Rey is stuck in the middle of nowhere and Finn is just about to take his first step on stage. They have origins to show, he’s already off and running.
