What a great idea for an anthology! Half the stories are about zombies, half the stories about unicorns, and connecting them all is the ongoing snark of the editors, both of whom are extremely partisan towards their chosen creature... and unrelentingly negative towards the other. Surprisingly, come the end of the book, I found myself solidly on Team Unicorn. I can't say I've ever been terribly excited about unicorns before - compared to the rest of the mythological animals they've always come across as a bit boring, to be honest - but the best three stories in here, by far, were on the side of the pointy-headed horses. "A Thousand Flowers" by Margo Lanagan, "The Care and Feeding of Your Baby Killer Unicorn" by Diana Peterfreund, and the hilariously, awfully named "Princess Prettypants" by Meg Cabot were all great. The rest of the stories were okay, but those three were the only ones I'd go back to. And I believe that Peterfreund has a series on the killer unicorns which I'm going to have to look up, because that one was, I think, my favourite.
