[Siren Classic ManLove: Erotic Alternative Paranormal Romance, M/M, shape-shifters, HEA] Riley Stevens is a deficient Omega who can’t shift. Even worse, Riley has no reliable mate or pack to fall back on. Taken by human scientists eager to take apart and study the supernatural, Riley thinks all hope is lost...until the transport convoy he's in is attacked by a powerful dominant werewolf. Zack Simmons is supposed to be watching the Darkfall Mountain Pack’s borders and warn off intruders. When his wolf catches wind of Riley’s scent, Zack abandons his post and attacks a human convoy. It's strange, Zack is usually calm and logical, but something about Riley calls to the dormant primitive urges within him to protect and keep. It's full moon season and he suspects Riley is his mate. But Zack has never committed himself to one man before and Riley is terrified to trust again. Can they make things work? A Siren Erotic Romance
