Can anyone help me find a book I read a while ago? It was a werewolf story, where the male mc didn't want a mate but he ended up finding her anyways. He found her living in the woods and she was a nymph (I think) and she ended up leaving with him. And in the end his cousin (who he's super close with ) dies and he goes on a frenzy and the female lead is pregnant, and tries to run away with the baby with the help of the he second male lead.
