An all-star line-up of children's book authors debate the question which is better: zombies or unicorns? The editors of the new collection Zombie vs. Unicorns, Holly Black (The Spiderwick Chronicles) and Justine Larbalestier (Liar) (pro-unicorn and zombie, respectively), gathered strong arguments for both sides in the form of short stories by an eclectic group of YA novelists. At this event the editors are joined by contributors Maureen Johnson (13 Little Blue Envelopes), Libba Bray (Going Bovine), Scott Westerfeld (Leviathan), Naomi Novik (Temeraire series), and Alaya Dawn Johnson (Racing the Dark), who will argue for their side. What side are you on? Team Zombie or Team Unicorn? Ages 10 and up.
