This is book 4.
Life on the run, with a heritage you never asked for, isn't easy for Taylor. The witches came at her hard, but she fought for a chance at life and destroyed Halo's Diamond so they couldn't sacrifice her. But now, the witches and werewolves want revenge and will stop at nothing. Taylor and her friends decide to seek refuge with Jesse's father in the mountains of France. The ancient castle sits on a beautiful mountain top deep in the French Alps. But will it be enough to keep Taylor safe from so many immortal enemies?
