Here's some info cut and pasted off the Kickstarter website:
THERE'S A ZOMBIE IN MY TREEHOUSE! is a book written for children of all ages by Ken Plume & John Robinson and drawn for children of all ages by Len Peralta. It was, however, created specifically with you in mind.
How can we be so sure of this?
Well, this is a children's book project that involves zombies--and you're reading this page. That says a lot about you, and we salute your morbid and whimsical nature. We ask you to embrace it...and read on.
The story of TREEHOUSE! involves our young hero, Johnny Fry, who loves his treehouse. It is his base of operations for imaginative adventures where he can be a pirate, a cowboy, or even a pirate-cowboy. But one dark day, a zombie somehow finds its way into his treehouse. And Johnny is no fool--he knows that playing in a zombie-infested treehouse is not a safe notion, so he stays away. His family tries to help him face his problem--tries being the key word there--and hijinks, mayhem and mystery ensue.
We had a lot of fun making the book. We were very happy that Wired liked it as well. And now, as we've marched into the future, these things called iBooks have come along. And we realized they could give us a chance to merge the physical book with an audiobook version. And not just one...but several. So the idea was hatched to use Kickstarter to fund the creation of the There's a Zombie in my Treehouse! iBook, complete with audio versions of the book from awesome celebrity narrators.
But then we thought: "Why stop there?" We have also kicked around the idea of a sequel in which our hero, Johnny Fry, is brought face-to-face with another incredible menace: Evil Snowmen.
