His Rejected Mate by Lindsey Devin

The show is over, but I’m not giving up on our love without a fight…
The deadly hit television show The Reject Project may have stopped filming, but that doesn’t mean we’re done fighting for our lives. We’ve been abandoned on the island while war wages on the mainland, and Kira’s been kidnapped by a dangerous scientist.
When I launch a rescue party to save her, we make the sickening discovery that Simon’s experiments are more terrifying that we imagined. Somehow, we have to stop him and figure out a way off the island.
And even if we reach Fangmore City alive, there’s no guarantee we’ll be able to protect ourselves and our loved ones from the brutal pack warfare or settle the score with the show’s producers.
Worst of all, Kira is starting to doubt our relationship because of others’ disapproval.
The entire world may be against us, but I intend to show her that our love is worth fighting for, even if it kills me…
