Once again we have to thank Kelly’s fabulous, patient, and detail-oriented agent, Renée Zuckerbrot, for keeping us on track and (as much as she can) honest. Then, of course, all the authors who sent us such dark, horrible, bleak, excellent monster stories; especially Cassandra Clare and Holly Black, who sparked the idea for this book. Thanks to Holly Black, Cassandra Clare, and Sarah Rees Brennan for substantial and timely help with the pop quiz. Thanks, too, to the Commonwealth of Massachusetts for its wonderful health care.
