Lucas is a werewolf who spent almost entire life in animal form. He doesn't know how to be human. But he is now obligated to be. And for that he is miserable.
Sarah is a human, she is kind and sweet and knows nothing of werewolf world. She leads a simple life that is perfectly planned.
But some plans are destined to fail. Some things are destined to happen whether we like it or not. Some souls are designed for each other, no matter what the cost is.
