The Highest Justice — Garth Nix

It's a question as old as time itself: which is better, the zombie or the unicorn? In this anthology, edited by Holly Black and Justine Larbalestier (unicorn and zombie, respectively), strong arguments are made for both sides in the form of short stories. Half of the stories portray the strengths--for good and evil--of unicorns and half show the good (and really, really bad-ass) side of zombies. Contributors include many bestselling teen authors, including Cassandra Clare, Libba Bray, Maureen Johnson, Meg Cabot, Scott Westerfeld, and Margo Lanagan. This anthology will have everyone asking: Team Zombie or Team Unicorn?
