The Reapers are the Angels, by Alden Bell, is one of the most beautiful and poetic zombie novels that I have ever read. And I'd never thought that I would describe a zombie novel as either "beautiful" or "poetic", much less both. Oh, don't get me wrong, there's violence, nail-biting fight scenes, zombies, monsters, mad scientists, and more. There's enough gore to meet the standards of even the most devoted zombie horror fan. There's also a nomadic, kick-ass heroine who is growing up in a world where the walking dead is the new norm, and yet she still retains some measure of innocence.
Alden Bell writes with a style of poetic prose that approaches the excellence of Guy Gavriel Kay. (And insofar as poetry expressed through prose is concerned, Guy Gavriel Kay is a master.) At least one of the other reviewers have called the book a Southern Gothic with Zombies, and while I'm not too familiar with the Southern Gothic subgenre, that seems to fit.
All in all, if you are looking for a well-written, innovative zombie novel set in a post-apocolyptic world, this is your read. It is a book that, with some adjustments, could be made into a movie. And yet any movie made of this book could not possibly do it justice.
