As Thrawn's TIE defender program is halted in favor of Director Krennic's secret Death Star project, he realizes that the balance of power in the Empire is measured by more than just military acumen or tactical efficiency. Even the greatest intellect can hardly compete with the power to annihilate entire planets. As Thrawn works to secure his place in the Imperial hierarchy, his former protégé Eli Vanto returns with a dire warning about Thrawn's homeworld. Thrawn's mastery of strategy must guide him through an impossible choice: duty to the Chiss Ascendancy, or fealty to the Empire he has sworn to serve. Even if the right choice means committing treason.

Sequel to: Thrawn: Alliances. Third in a trilogy.
