I got a kindle fire recently, it's the number one recommended tablet for college students, I read. As soon as I got it, I scrolled through the free books that were available for download. There are a lot of books on wicca, pagan alphabets, spellbooks, etc. And if they don't have what you're looking for, keep checking. I believe amazon does daily giveaways and sometimes the books are pagan themed. Now whether or not these books are life changing, I'm not sure, but if you're an avid reader like me and are willing to read anything (and of course if you have any sort of kindle or nook, or other reading tablet) go for it!
