Challenging Gunner - Hidden Breed, #2

As hybrid shifters, Gunner and his siblings shouldn't exist. Until recently the shifter communities did know about them or the lab they came from. After one of his sisters is attacked on wolf territory, his family is in more danger than expected. More hybrids are being created and weaponized. It's up to Gunner and his family to take down the organization that created them. When a decision is made to return to the lab where he was born, he isn't sure how he feels.
Being paired up with bear Alpha, Zara Black, for this mission stirs a dangerous desire he isn't prepared for. Because the beautiful female is his mate. And he must push her away. Will the attraction between them be enough to risk the danger? Or will it pull them further apart?
