I'm going to recommend a basic candle book by Raymond Buckland:

very quickly, but if you're really starting from zero, this is better than nothing.
The basics of any candle ritual involve a candle and a ritual. :) This book will help you formulate the beginnings of a ritual framework, and you'll quickly develop your own that fit your own worldview/spirituality.
If you're more interested in Goddess/Earth-based spirituality, I'd recommend picking up
The Spiral Dance by Starhawk. She barely touches on candles here, but she'll give you the basic ritual framework (ground and center, call the quarters, etc.) that you need to do any sort of ritual. Once you have that foundation, you'll be able to use the candle as the focus of the center of your ritual.
