Pearson Foundation has an amazing new initiative that allows you to see many of their books free online. www.wegivebooks.org/books allows you to see many of their books in full color, full length for free. There are 2, 320 to date on the site. I like the site because the free books are ones that you have actually heard of, by well-known authors, and the books don't have annoying sounds attached. Currently the age focus is 10 and under but it looks like they are working to add a section for 11 to 13 and for teens.
