An Uncommon Whore: The Lost King Series - Lost King

Pasha is a slave, whoring for travelers at the most treacherous bar on Warlan. The day Pasha spots the dangerous pirate in the bar, he knows he mustn't let the stranger slip away, no matter what he must do to draw his attention.

Captain Griffin Hawke spent the better part of a decade searching for his lost king, only to find Helios Dayspring crouched between his legs, swathed in the robes and shackles of a whore. Though he is appalled by the downfall of his king, Grif falls for the sensual creature who has taken his place. After a brutal invasion stripped his people of nearly everything, they desperately need Helios to lead them. But returning him to throne means smuggling him off the planet, disabling the chip that keeps him submissive and forgetful. They will face old enemies, traitors, and greedy opportunists who'd like to strip their new planet of its wealth.

It might mean Grif losing his lover... and they've both lost too much already.
