Small h has always lived with the other H's in a city surrounded by walls that keep them safe. At least, that's what the big H's say. But one day, a hole in the wall reveals someone new on the other side. When little h and little i meet, they make a small word with big meaning: 'hi!' The other H's find out, though. They fill the hole. But it won't be enough to keep these little letters apart - or twenty-four of their newest friends. Every Little Letter shows how even the smallest among us can make a big impact, and how a single act of friendship can inspire whole communities to come together. How do you tear down walls? With words, at first. Then brick by brick.
