Books with title Wizards Rule

This is the fourth book in the Rule Series and was previously known as Warlocks Rule. Jack and Silver's story continues two years later after he's disappeared with his vampire friends while she is working hard to find a cure for him. She is desperate to return him to mortal form, so desperate that she's willing to risk her own life and seek out the one powerful entity who might be able to get rid of Jack's fangs. She's afraid Jack is moving on.... and he is. Because he's realized she won't get on with her life until he does, he stops visiting her in her dreams. But when he finds out she's on the verge of making a fatal mistake, he returns to Bliss to save her.
