The first book of best-selling sci-fi author Jack Campbell’s new series Beyond the Frontier returns to find Captain John “Black Jack" Geary, the hero of the Lost Fleet series, awoken from cryogenic sleep to take command of the fleet. Geary’s legendary exploits have earned him the adoration of the people—and the enmity of politicians convinced that a living hero can be a very inconvenient thing.

Geary believed in the Alliance. Even when he uncovered overwhelming evidence that the highest echelons of the government and fleet command were involved in secret programs and prison camps, he believed it was worth saving. He believed his duty was to see that justice was served even though some factions feared that revealing the truth would cause the Alliance to crumble. But after narrowly surviving two assassination attempts when he brings evidence of the misdeeds to the capital star system, Geary realizes that some want to get rid of him.

The world of Dematr had been locked unchanging for centuries by the Great Guilds, most people living in a world of oil lamps, crossbows, and horse cavalry, the Mechanics reserving to themselves the technology for steam locomotives, rifles, and far-talkers while the Mages treated all others as if they were nothing - until Master Mechanic Mari, dragon slayer and pirate queen, and Master of Mages Alain raised the army of the new day to free their world.

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052.

We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....
