Book excerpt: Jaesin Grean has one priority. He wants to keep his best friend, Dr. Luciana Doll, safe from her father and a bunch of zombies wandering around outside their door. Lucy is a genius and is close to developing a cure. When her ex-fiancé, Nathanial Tyger, shows up infected she is forced to move her timetable up, hoping to save him from a future as a zombie. They race against the clock to save Nat and fight off a possible attack from her father. Will they survive in a world already torn apart? Jaesin is given the herculean task of guiding them through it all. Will he live up to Lucy's expectations and can he keep her safe long enough to find a cure.
