Torran by Leslie Chase

Stranded on the wrong planet, captured by brutal alien raiders, the only good thing about Lisa’s situation is Torran. He’s a dangerous alien warrior – who also happens to be the hottest man she’s ever met. Strong, protective, and lethal, he’s everything she could want or need.
Perhaps she shouldn’t have shot him on sight?
Torran is used to surviving alone on alien planets, but this time he has others to protect. Another complication is the human captives. One human in particular. The female fate has infuriatingly chosen for him, the one he is now compelled to do anything for.
He’ll just have to overlook the fact that she tried to kill him.
When the alien leaders threaten to kill Lisa and her family, Torran has to choose between his own people and his mate. But even if he can get Lisa to another human settlement, will he be welcome there? Or will the humans’ fear of him drive them apart?
