Perilous Shield — Jack Campbell

A thrilling spin-off from Jack Campbell's The Lost Fleet series, The Lost Stars: Tarnished Knight delivered tales of space battles and struggles against tyrants and aliens. Now the New York Times bestselling author returns with the next chapter in the overthrow of the Syndicate Worlds' oppression...

Following a successful coup, the leaders of the rebel Midway Star System struggle to forge a government free enough to please its citizens yet strong enough to secure power. But in a world where former rulers have become new foes, an alien threat to humanity may turn old adversaries into uncertain allies.

General Artur Drakon knows three words describe someone who confides in a Syndicate CEO: Stupid. Betrayed. Dead. Despite his misgivings, he partnered with another former CEO to overthrow Syndic forces. Now, with an enigma fleet menacing their hard-earned independence, he can ill afford to trust her -- or lose her support.

President Gwen Iceni believes Midway is humanity's defense against the enigmas. Syndicate training taught her self-preservation in a crisis, yet she's determined to fight for the star system's fate...even if it means joining forces with Drakon -- and an officer of the hated Alliance.

Their plan places the Midway flotilla at great risk in hopes of greater reward: recruiting the personnel necessary to man warships against the enigmas. But before facing the alien advance, Drakon and Iceni must survive hidden dangers closer to home: all-too-human threats that could jeopardize Midway's freedom...and their own lives.
