A physical copy of the book that can be summoned at any time, regardless of your access to power or Internet, but could still be destroyed by fire, water, wild animals, or my friend Tim after I kick his ass in Halo. Seriously Tim, I'm still pissed and you still owe me a book. Jerk.
A signed copy of the physical copy of the book, as well as a digital copy of the book. I figure this way you have your bases covered as best you can, and in the event that you survive the first wave you might even be able to use my signature as barter for something. I have terrible penmanship, so you can just tell them it's someone famous.
A signed copy of the physical copy of the book, as well as a digital copy of the book. This option is for backers who are not in the US, but would still like to meet the Space Monster horde with dignity and maybe a pile of napkins so whichever horrifying beast you choose to appeal to can clean up afterwards. You're so polite and thoughtful!
Proof of your death at the hands of the space monsters in the form of an official GETRI Incident Report. This report will be written specifically for you, and printed on high quality paper.
Also includes signed copy of the physical copy of the book, as well as a digital copy of the book. You won't ever read either of them, because you'll be so busy showing everyone proof of your death that you'll use up all the time you have left.
Two signed copies of the physical version of the book, as well as access to my Hangout schedule so you can check in on me and see how the book is coming. No guarantee that what you will see in those Hangouts will be pretty, and there's a reasonable chance that I will yell at you if you make noise while I am in the zone.
Joking aside there's a reasonable chance the people in the Hangouts with me will be mentioned occasionally in the book. After all, gotta have victims right?
Direct involvement in the book, as well as up to five signed copies to do whatever you want with. This is your best chance for survival, because you can keep one in a plastic baggie and use the others to make a fire or defend yourself in situations where that might be necessary.
You'll be invited to private Hangouts, have access to my entire workflow, and have a say in several key points in the book. You'll also be in a special section of the book, which I will dedicate to important people.
