Evan is the reclusive librarian of Honeycutt Academy, and a source of curiosity among students and staff, most notably the bubbly potions teacher. With her by their side, Evan is willing to give love another shot and move on from a devastating breakup. That's complicated by the arrival of Evan's half-sister, who reopens old wounds for them—painful childhood memories of the father they share. A reluctant Evan is pulled into a plot to slay the vampire, but neither are suited for the task. But they know the perfect person for the job—a wolf shifter, part-time monster hunter—and an old flame, who may threaten their newfound relationship.
