I am sure you will find here enough reading to learn a lot. William Lilly is one of the best sources to learn Astrology, so you are armed and if you are a commited student, soon you will be doing Horary readings. Your own and others'.
You might be interested in getting the 3 volumes of Christian Astrology for free on internet (right here on the forum, I think), in case you only have one.
