With the Imperial forces locked in a gruelling war of attrition over the dead hive city of Vesperus, a former ace fighter pilot returns to the cockpit as the Aeronautica risks it all to secure Interceptor City for the Imperium.

Former ace fighter pilot Bree Jagdea’s days of high-octane, white-knuckle dogfights are long behind her. Content with executing supply runs for the war effort, Jagdea considers herself retired. But when enemy forces start a relentless bombing campaign through the hive city of Vesperus, Jagdea is forced back into the Aeronautica – stationed with the infamous Circus 66 squadron, executing near-suicidal dead-drops and blistering interception runs through Vesperus’ lethal rat runs.

Plunged back into a world where the smallest of errors means instant death, can Jagdea outfly the enemy aces, secure Interceptor City for the Imperium, and return to solid ground with her sanity intact?
