Amazon has a new way to reel you into Audible now that smart speakers are a big deal: give you a freebie just by asking. As of this week, anyone who's new to Audible can ask an Echo speaker to read a full audiobook at no cost. You don't have to be picky about your choice of book, either, so you can ask for the hot new novel if that's your preference. Naturally, Amazon is hoping you'll be so enamored that you sign up on the spot -- if you aren't, though, you can at least say that it didn't take much effort to get that free book in the first place.
