USS Hamilton: Ironhold Station (USS Hamilton #1)

The surprise attack within the Auriga Star System was worse than brutal, it was heinous—leaving the US-Navy's 3rd Fleet decimated. Thousands of crew are reported dead, including the ship’s Captain. Reluctantly, the young XO, Galvin Quintos, will be taking command of the fleet's crippled dreadnaught, the USS Hamilton, while doing his best to bring fleet survivors back to Earth. Going from bad to worse, there’s a murderer running loose onboard the ship. Add to that fuel levels are critically low, and the Grish are back and in fast pursuit—ready to finish what they’d started. Only by sheer luck, along with a good measure of cagey smarts, will Quintos be able to rise to the challenge.
