Book excerpt: This horrifying exclusive eNovella is a thrilling companion to bestselling author Darren Shan's Zom-B series! Cat Ward believes that the world punishes the weak. As a high school teacher, she has witnessed the way people exploit every vulnerability, which is why she steels herself against her class of indifferent, disruptive students-none more despicable than B Smith. Cat's philosophy is put to the test when zombies overtake the school and the rest of London, and she must do whatever it takes to survive. But her decisions may come back to haunt when Cat encounters a nightmarish mutant clown named Mr. Dowling and the terrors that await beneath his circus big top.
