Looking for a Charity

Hi everyone, I was hoping maybe someone out there in the blog world could guide me. I am looking for a charity that involves children and books. My 1 year blogoversay is coming up and the prize is Amazing! So i wanted to be able to incorporate the charity so they can possible gain from my giveaway. So this is where you all come in. If you have suggestions please send me a EMAIL. I would prefer like I mentioned earlier for it to be book and children related. Thank for taking the time to read this.
