Let's start with my absolute favorite monthly horoscope, Susan Miller's astrologyzone.com. Miller's a certified astrologer with a huge following because she writes lengthy, detailed, highly specific monthly forecasts for each sign for free. They appear around the first of the month, and they are so good that another horoscope site, which does fairly good daily and weekly scopes, www.dailyscopes.com, refers you to Miller's site for monthly forecasts.
Miller offers daily horoscopes by email for $4.95, and I'm tempted, but by searching I thought I'd found a place where I could read them for free. I was wrong. When writing monthly forecasts Miller will refer to the reader, distinctively, as "dear Aquarius" (or "dear Virgo," or whatever). I'd found a daily scope that used the "dear" and sounded so much like Miller I was convinced. But Miller assures me that those are not her scopes; they are the work of imitators.
One year I ordered Miller's wall calendar but did not like the dark and swampish New Age paintings that served as their illustrations. But Susan Miller, astrologer, has my total respect and -- trust me -- that's saying a lot. Five stars out of five, especially for those two-thousand-word monthly scopes!
