Captured

"Living in Jackson's cold embrace, Serenity no longer remembers who she is. Repeat feedings have left her a mere shell of a person and she has no recollections of her past life, though the sense that she isn't alone often haunts her. Back in Los Angeles, Sebastian has never given up hope of finding her again. Their daughter, Elizabeth, experiences visions of Serenity's new existence and together they track her across the country. But finding Serenity might prove to be the least of their problems. When Sebastian seeks the help of an older vampire, Demitrios, the family find themselves in the fight of their lives." – quoted from this book's product page on Amazon.com as of 2017-12-21.
