hi, welcome to SoM, if you wish to learn about Wicca, i'd look for Wicca: A Guide for the Solitary Practitioner by Scott Cunningham and/or Wicca for Life by Raymond Buckland.
if you can't buy the books, or your library doesn't have any, you can find some in google books. i've checked, while they don't have all books by Buckland or Cunningham, they do have quite a few, so that might be of use to you.
Welcome Luna! Feel free to check out the faq section and make sure to read the SoM Survival Guide and the Getting Started on SoM article in the articles tab. For books on Wicca I suggest you take a look at my profile. At the bottom I have a selection of links that provide free ebooks. Darkbooks.org would be your best bet. Welcome to SoM and if you have any questions just ask.
