I recommend the novel " Life with Wolves ". The male protagonist is a werewolf who will transform every full moon. The female protagonist is a human. In the story, due to the intervention of his ex-girlfriend, the male protagonist mistook the female protagonist for an enemy and almost killed her. However, as the plot developed, the male protagonist slowly realized the importance of the female protagonist and parted ways with his ex-girlfriend. The main storyline was a love story between the male and female leads, plus an interesting werewolf transformation setting. I hope you will like this novel.😊
