A Greater Threat (Retrograde Cycle, #3)

Captain Celia Grey is tasked: Aliens have her ship locked down, but her crew have begun to fight back.

The good news is that help is on the way, courtesy of a detachment of Marines aboard the BPOE Rosalind Franklin. Celia will need all her skills, a little luck, and whatever help she can get to save the lives of her people.
