Doom Protocol: Ether War Book 7 by John Walker

A desperate battle has left the Morrigan crippled in a distant system with no backup and little hope. Outnumbered, outgunned, damaged, and stuck, they must find a way to survive the conflict by any means necessary. Captain Markel and his crew are left with no option other than fighting to the end. As their goal shifts to one of pure survival, they prepare for what very well may be the end.
