The concept isn't very new, but the images are lovely. I really like the idea that the people in Carmelita's neighborhood 1) greet one another and 2) know one another well enough to offer greeting in an appropriate language. But, I sometimes wonder if such a neighborhood really exists (and if so, where is it?! Maybe somewhere in NYC? Because definitely not Boston, Chicago, DC...). This book could be helpful in showing young children that there are many languages, all of which are valid, and that friendships can be built across languages, but as a stand-alone book it won't do much for advancing relationships across lines of difference. It needs to be used in collaboration with other texts that will help children give language differences a richer context.
