Unputdownable

I was at the Book Depot and found the word "unputdownable" on three book jackets (and I wasn't even searching for it). I came home and picked up the book I am currently struggling not to put down, Tom Wolfe's I Am Charlotte Simmons. When I turned it over I found the words, "Another unputdownable novel from the author of The Bonfire of the Vanities" on the back cover. Made me want to put it down. I think whoever came up with this word should be put down. So there!
