Thrawn: Treason

Thrawn: Treason is a 2019 Star Wars novel by Timothy Zahn, published on July 23, 2019 by Del Rey Books. It continues the chronicles of Grand Admiral Thrawn, a character that Zahn originated in his Heir to the Empire trilogy published in 1991–1993. It is the sequel to Zahn's Thrawn: Alliances novel, the third installment of the newer Thrawn trilogy, and the tenth Thrawn novel overall.

Development
In December 2018, Lucasfilm and Del Rey Books announced that Timothy Zahn, the author of the first nine Thrawn novels, was writing a sequel to the Star Wars: Thrawn and Thrawn: Alliances, comprising a new Thrawn trilogy. Zahn said about writing Thrawn: Treason: "I'm playing both sides of the chessboard, [nor do] I want stupid villains or stupid heroes. That's boring. I want both sides to be smart within their own parameters, within the range of what they know, and so it's a matter of both sides are clever. I usually go in knowing which side is going to win and I work in that direction."

Reception
Thrawn: Treason placed The New York Times Best Seller list for Hardcover Fiction on the August 11, 2019 edition, and stayed there for three weeks, placing fifth.

Megan Crouse of Den of Geek wrote that Treason is "a solidly constructed story that includes a lot of almost-explored threads worthy of their own novels."
