Because how could it *not* be?!?!
This was found, along with the covers and titles of many other self-published books, at Self-Published Books. It's a great site, make sure to check it out. (Thanks to lilithsaintcrow for tweeting the link!)
By the way, this book is the fourth in the Multiverse series. I wasn't able to immediately find them at the storywrite page, but I'm sure they're there. Also, it appears to be a screenplay! Michael Bay is set!
