Thought I'd share a post from Free Homeschool Deals. There are a bunch of free downloads (if you don't have a Kindle you can still download to your PC!) for middle and high school math, science, history, etc. http://www.freehomeschooldeals.com/free-kindle-books-middle-school-and-highschool-textbooks/
Awesome! Thanks for sharing! Not sure if anyone else clicked around a bit, but I found the company's own site that also looks really interesting. Including a K-12 Math and Science site that they acquired called Braingenie. It all looks really interesting!
Thank you so much for sharing. I had browsed Amazon and found a couple of these books but this list is great!! So glad you took the time to share!!
