Another well written, engaging Young Adult novel: Rebel Rising (Beth Revis, 2017). This tale slots into the space between Catalyst and the Rogue One novelization.
Who wants to learn the sad history of Jyn Erso? Just finished reading about the intervening years between when Saw picks her up as a little girl hiding in a cave on Lah'mu to the time the Rebels pick her up as prisoner Lianna Hallik riding in a turbo tank on Wobani.
During this book, Jyn is not a Rebel with a capital "R" in the tradition on Mon Mothma. She also doesn't fit in with the quasi-terrorist Rebellion outcasts like Saw Gerrera, even though she spent a lot of time with him and had great affection for him. She blames equally the Empire and the Rebellion for the sad state of affairs in the galaxy. She simply wants to be left alone, but events and circumstances never allow it. A Star Wars tragedy to be sure.
A nice addition to my preferred canon.
