He should have left her and never looked back...But things turned out completely differently for Cain, an almost thousand-year-old Guardian who should have been more careful. Instead of leaving years ago, he looks after the only person who touched his heart. He stays to protect her, or at least that's what he justifies to himself. When trouble strikes her, Cain knows he should simply minimize his own losses and leave, but the struggle for the child who became a woman falls on him. Now each of them will have to pay a price. Danny knows that she is not technically a Protector, but she puts her life in danger every time she goes out on patrol. This doesn’t bother her, because that’s her job. And this is the only thing that matters to her now, and she is not going to give up without a fight. Unfortunately, Danny did not foresee that her ex-boyfriend would sell her to the Master, she would be captured and locked up with the eccentric Guardian. The same Guardian who broke her heart many years ago and now looks at her as if she is to blame for everything.
