A great write up about the upcoming Mars Retrograde in Virgo.
Terrific info here about the potential for positive change within this retrograde. I find Mars Retrograde phases extremely challenging, so it was important for me to find this article, which points out the silver lining to be found during this time.

12 signs are 12 signs
12 houses are 12 houses
the degree that begins and ends a house is from one pt in the zodiac to another
it is very COMMON that you will have no house cusps starting or ending in Virgo; therefore neither in Pisces.
No big deal. Many say that planets contained within an intercepted house don't have direct open expression. I find
that very overrated. 
that you're going to be given time to rethink how you do things. Virgos are always gung ho about being productive. This rx period will encourage you to step back and reanalyze how you do what you do, once it goes direct in April, then you can start the conveyor belt rolling again. Nothing to worry about personally other that some possible irritation or tempation to fight for a day or two. Good luck.
so how will Mars retrograde in Virgo affect me? Or won't it?
Rick if you're around, care to chime in?
BTW - I ordered your book from Amazon yesterday - can't wait to read it! 
Having Natal Mars in Virgo surely means something here. As it transits back thru your 4th house, back into your 3rd, and then back out again later on....
It's quite a mixture.
1. It will have strong emotional effects since your 4th has much to do with how you act on your feelings.
2. Since it is next Uranus and Pluto in your natal chart, it really gets complex.
As you it is quite common for Virgos to suppress, or not even know, how they're feeling since they're so intensely attuned to doing what's RIGHT and being productive.... This will give you a chance to question how you are ACTING on how you feel. It's that simple. Have you been acting the way you feel or acting as you think you should (blech). You get a new chance here to renew your attitudes toward that.
Lots of people have come to see me in the past 3 years that have that Uranus/Pluto conjunction in Virgo. All people born during the 60's mainly. I have found that this question pops up when that axis gets stimulated:
"I have been good.... but what has it brought me?" Nothing wrong with behaving, but once again, we see this natal symbol of a volcano erupting has been so tamed for so long. What for? Has it served you?
This is the very energy that started AND ended the 60's, literally. Good luck
