Ghosts from the Past — Chris Hechtl

Fleet admiral John Henry Irons has been busy.
After waking in the Senka system he has crisscrossed the system, having a series of adventures and ups and downs along the way. He's made some new friends and met old ones. He has also made some powerful enemies.
But the call to war is inevitable. Those who thrive on destruction wish him and the civilization he is trying to rebuild ill will. The boot of oppression is already on a part of the sector thanks to the Nazi like Horathian pirates.
Admiral Irons must lead a rag tag group of former pirate slaves and military personnel back to one of the few places he hopes will help stem the pirate tide. Once there he'll have to face the politicians, then dig up his one ace, a secret from his past.
But some ghosts should remain buried...
