In select cities, you can see these. If you take your own picture of one, with or without you, and tag it (@Lissa_Price on twitter, #lissaprice on fb, send me an email if it’s on your blog), you will receive an entry to win the iPad Air that is part of the Enders pre-orders contest. And one winner will get a $20 gift card to a bookstore.
These are a few of them. For clues on the cities and malls, go to my FB page.
