Gratitude goes out to Aaron Percival and Adam Zeller, webmasters of AVPGalaxy.net, which is the definitive source of research online for this book and for many authors, for going above and beyond the call of duty in helping us navigate the complicated worldbuilding of the Expanded Universe. Their advice and insights were invaluable in keeping us on track.
Thanks to super-agent Sara Crowe of Pippin Properties, 20th Century Studios Franchise Management, and Titan Books—especially our editor Steve Saffel—for letting us play in this fun universe we’re fans of, and to all our authors for their hard work and dedication to getting it right.
Many thanks to the legion of fans of both Predator and Alien—for enthusiastic support and nit-picky technical info.
