Everyone knows that Hank Whitestone is a genius, but nobody knows the real story of what he invented and what happened as a result. But, for readers in years to come, when the story finally comes out, here is the true story of how Hank came up with his theory of gravity, and invented the Grav Buster, and how everyone built the spaceship Pegasus, and how the whole family traveled into space, and what happened up there. Of course, it wasn't that easy and a couple of times it was down-right scary—when we had to steal the nukes, for example—and the whole thing had to be done in secret, in case JJ figured out what we were doing and took Pegasus away from us. Anyway, if you have authorized access to "Hank's Idea" you can read this stuff now, provided, of course, that you don't breathe a word to anyone. Just to be on the safe side, please eat this book when you've finished it, in case it falls into the wrong hands.
