If you haven't already heard of Books for Boston, and haven't donated, here is a great project being run by AC Gaughen.
She is asking for authors and non authors to donate books for children. But before you send the book, write a message of hope, courage, or resilience.
Here is a link to the blog post and information about how to donate: http://www.acgaughen.com/blog/2013/4/25/books-for-boston.html
I think this is a fantastic project and I found that in writing my own message of hope, I felt encouraged as well. Hope you will too!
