Any local book shop, the will usually have a new age occult section. There are many kinds of spell books, but I recommend you to look through them til you find one that is interesting. I litterally spend about an hour or two sitting in the floor in that section looking through all the amazing books that they have. Hey, and if you can't find this section and your too shy to ask the cashier 'Excuse me, but where can I find a spell book?' You could ask something like, 'Excuse me, but could you tell me where I can find a book on Wicca? I'm doing a report for school.' Trust me, they wont judge you. lol.
