Flight of the Old Wolf - Against the Endless Dark, #1

A burnout captain. An obsolete starship. One more mission for both. Tenacity is the last of the Fenris-class battlecruisers, the "Old Wolf" as her crew calls her. Captain Dath Raker-storied, scarred, and outrageous-gets called worse. But the command's been his last, best chance to shine, even if it's just showing the Republic of Sanctuary flag while ferrying a delegation to peace talks. The Republic's deadliest rival has no interest in peace.
Deranged by centuries in thrall to obscene alien gods, the Golgothan Empire is ready to make their big move. And a meeting of the star-nations is a perfect way to get all their enemies in one place. The Golgothans' plan relies on surprise and the rapid collapse of resistance. They're about to find out that Tenacity is more than just a name.
