Jack Campbell The Lost Fleet

New York Times bestselling author Jack Campbell continues his "series of fast-paced adventure" ( SFRevu ) as The Lost Fleet: Beyond the Frontier continues... Admiral John "Black Jack" Geary and the crew of Dauntless have safely escorted important alien representatives to Earth. But before they can depart for home, two of Geary's key lieutenants vanish.

But what he finds there is a danger much greater than anyone expected: a mysterious threat that could finally force the Alliance to its knees...
