Thrawn: Alliances is the best of both worlds. Timothy Zahn combines movie characters that have been loved, with newer characters in one space and time, piecing together the final story over two timelines. This novel is a great piece of work, with flow only Zahn could have accomplished. In terms of main characters, there’s Anakin Skywalker, Padme Amidala, a young Thrawn, Darth Vader, an old Thrawn, and of course, characters introduced in Star Wars: Thrawn. A huge plus is the inclusion of another Star Wars: Legends character, a Noghri named Ruk!
Resistance Reborn by Rebecca Roanhorse takes place after Star Wars: The Last Jedi and before the upcoming conclusion to The Skywalker Saga, Star Wars: The Rise of Skywalker. During the year long gap between the two, Resistance Reborn takes place, presumably on the earlier side. In short, the Resistance is looking for a place to hole up after Crait. Poe with his squadron has already picked up some borrowed ships and are trying to find people to join up. The call Leia placed at the end of TLJ has continually gone unnoticed. The Resistance has found out potential leadership are being picked up by The First Order to prevent them from joining up. The goal of the Resistance in Resistance Reborn is to rebuild the Resistance, turning the droplets they have, into a mighty ocean to beat The First Order.
Star Wars: Thrawn is the first real introduction of a Star Wars Legends character into current canon mythos. That character being Mitth’raw’nuruodo, or Thrawn as he is called by most. Thrawn is a Chiss, a species that is part of the Unknown Regions territories in space. The species is rarely seen around the galaxy, and it is often thought they were a myth. This novel follows Thrawn’s introduction to the central worlds a couple of years after the Empire was formed in Revenge of the Sith. It serves as a prequel to the third season of Star Wars Rebels, introducing the characters of Arihnda Pryce, Grand Admiral Thrawn, and Commander Eli Vanto. Though Vanto is not present in Rebels, his character is a vital part of Thrawn’s plot line.
