Change of Fate (The Briar Creek Vampires, #4) by Jayme Morse & Jody Morse

When Lexi and Dan were sucked into the book, they left their world as they know it behind. Stuck in a strange, new place with only each other for support, Dan and Lexi begin to confide in each other. Will they settle their differences? Or has Lexi traveled back in time with the one person in Briar Creek who had always had it out for her from the very beginning? Meanwhile, Austin, Gabe, Anna, and Craig scramble to find Lexi's father, the only person who might know how to bring Dan and Lexi home.
