There are several organizations around the country that work to get books into the hands of children in lower income communities. First Book is one of the best. In fact, they're about to celebrate the distribution of their 50 millionth book! To celebrate, they are asking you what book got you hooked on reading? You can vote at their website (click the logo) and choose the state you'd like to receive 50,000 brand new books for children in need. So go vote!
Thanks to Reading Rocket for the heads up!
