This is Book One in Carin Rafferty's acclaimed Sanctuary series. When Ariel Dantes's twin brother disappears, she goes to the last person known to see him-Lucien Morgret, a self-proclaimed warlock. Ariel doesn't believe in witches and warlocks, but Lucien not only looks the part, he does appear to have some type of psychic powers. There's no other explanation for the strange and terrifying things that happen when she meets him. At first Lucien refuses to help Ariel, but then he suddenly appears in her home and agrees to go after her brother, but under his conditions. Ariel doesn't want to trust this sexy man who scares the daylights out of her, but if she wants to find Armand, she doesn't have a choice. Ariel finds her world turned upside-down as Lucien helps her infiltrate his coven. It soon becomes clear that the only chance she has of saving her brother is to sacrifice her soul by letting Lucien cast a spell over her. But will his spell be strong enough to defeat a rogue warlock practicing the forbidden Old Ways, or will it backfire and condemn them all to death?
