Quinten's Revenge by K.S. Augustin

After seven years of enforced isolation, Quinten Tamlan is back on his game and he wants the head of Faks Somen, now leader of the Mitres Raygun pirate cartel, on a platter. There’s only one problem: he only has one ship and two other crewmembers, and that’s not good enough to go up against a well-protected gang of cutthroats.

Knowing he needs allies, Quinten attempts to track down the old members of the ST Alliance, but they’re all dead. The only people willing to assist him are an old pirate and the son of someone he once had a lot of respect for. But the old pirate is the mother of the man who last betrayed him, and there’s something very mysterious about Delee’s son.

Meanwhile, Faks is holed up somewhere, laughing at him. But, Quinten vows, not for much longer.
