If you know any kids or hang out in bookstores, you've likely encountered the "Good Night" books. The one most commonly seen in these parts is Good Night Vancouver, in which an unseen narrator, à la Goodnight Moon, says good morning, hello, goodnight, etc., to various city landmarks.
My family happened to receive a copy of Good Night Vancouver a few years ago and another one recently. At first, my only thought was, "Oh good. Now we have a new, less-chewed copy." But something felt different reading the new one: there was a new page, or rather, a page showing kids looking at a beluga whale at the Vancouver Aquarium had been replaced by one depicting the water park at Granville Island.
Whatever the source of the change, it's one that certain activist groups would likely approve of, with the continuing controversy about the aquarium keeping cetaceans in captivity.
Good Night Vancouver was first published in 2010 and is ranked 8,145 in Books on Amazon.ca.
