Unputdownable

Believe it or not, this is a real word, the first known citation being by Raymond Chandler when in 1947, he was quoted as saying of a book that it was unputdownable. As in once you pick it up and start reading it, it's so riveting, you can't put it down. Well in fact, what would you use to describe other than a book? Well, maybe these days, you might use it to describe an app or device. A few books I've found unputdownable are Ragtime, the Hannibal Lector series, Shogun and pretty much any Elmore Leonard book. How about you?
