Excellent Story
Format: Paperback
Charles Soule is without a doubt one of the greatest Star Wars authors around. With this comic he keeps the reader on their toes making it hard to set the book down. It is a definite page turner and easily one of the best comics Marvel has out out under the Star Wars name. An intriguing story, unforgettable moments, and packed with lore, Star Wars fans are sure to love The Rise of Kylo Ren.

Ben Solo’s fall is tragic
Format: Paperback
We don’t know much about Ben Solo’s past, but this comic explains a little bit more about why he is the way he is. It also explains that he didn’t do all the things he himself implies in TLJ. It’s a story of a young man who is lost because those he is supposed to trust betray him, which is exactly what Snoke/Palpatine want. It shows he didn’t really have a choice in the path he took and it makes his redemption at the end of the saga powerful, even if the last movie itself destroys the myth of Star Wars. I love knowing that Rey and Ben have always had a connection and I hope that is something explored more deeply in Episode X when they bring Ben back.
