Going Bovine, by Libba Bray
There’s so much going on in Going Bovine, a Printz Award-winner from the author of the successful Gemma Doyle trilogy, that it can be exhausting to read. But it’s well worth it. After being diagnosed with fatal mad cow disease, Cameron soon finds himself in a hospital bed chatting with a really cute angel who gives him a quest that she promises will lead to a cure. It’s a novel that deals with mortality and talking garden gnomes with equal expertise.
