Rogue Wolf by Violet Hilton
Captain Trent Rolston knows his space pirate crew isn’t the biggest or the best, but that doesn’t keep him from diligently finding new targets to pillage. He also has a more personal mission: to discover what’s been haunting his mechanic, Vince, and convince him they could be more than friends.
But Vince is harboring deep secrets. He’s living his life on the run as a human, hiding his alien heritage, hunted by his own tribe for daring to love an enemy. Despite his fidelity to his deceased partner, Vince realizes he’s still affected by the mating cycle, and the drive to claim Trent is too powerful to avoid for long… and Trent isn’t helping, despite the danger as Vince’s tribe tracks him down and marks the lovers for death.
