Analysis
So he is ASC Scorpion with Moon debilitated, Jupiter and Ketu in the Lagna House; Rahu in the seventh; he has mild Kaal Sarpa Dosha (MKSD) and he is a highly imaginative and emotional person by nature and his profession of non-fiction has helped him channelize his negative emotions and sufferings since birth in an very assertive and good way. So from that point of view he is lucky and the luck comes to his him despite the challenges in his life due to all planets being in auspicious houses. That does not mean he has not faced challenges in his life; he comes from a broken home; father left him when he was two; mother raised him up single handedly; so childhood must have been tough but he was lucky enough to be approached by a stable and romantic partner for life; his wife since 1971. His married life and his wife play a very significant role in his life and their charts are complimenting each other. So his chart analysis is incomplete without the chart analysis of the wife which I will also do. And hence I would call his chart as getting “astrological spousal support”. Rahu in this 7th house means that somewhat tough times the couple face but were able to get through it. Now as I mentioned; he is a very emotional and sensitive person; so unless the wife has a complimentary temperament he would have been Stephine King. Also he is not that romantic, while she is extremely romantic; so that balance is there and that is why he has spent all his life with her and he has channelized all his nightmares from childhood into horror novels for which he has become world famous and very wealthy. Not only that he has become father of three healthy children. So that is due to his lagna house which would have ensured that writing non fiction was the perfect professional fit for him; other than being self employed. This as he is so emotional that he is not made for a 9 to 5 job. He would have been horrible in that but destiny has helped him a lot and very early in his life from 1971; he has been married and the weak planets have been boosted or helped by the spouse; whose chart analysis I have done below. Now 9th house has Saturn and Mars debilitated. So this means professionally he will do very well but he will be argumentative to the point that if he starts arguing, you cannot win the argument; this aspect also he has channelized via his imaginary mind by writing novels which are scary; because he not only uses them as a pressure relief valves for his negative emotions but also and outwardly it allows him to remains a reclusive person. He is not known to be outwardly very friendly or very popular friends of friend. He lives his own private and wealthy and professionally rewarding life on his own terms and for that to a great extent luck has helped him. This as his 11th house is also extremely auspicious overall because what happens Mercury exalted in the 11th house; means that he is basically a very nice person genuine general human being who despite his sufferings will keep them inside of him; he will not express them outwardly and will know how to channelize his emotions gainfully. Mercury exalted means that name, fame, travel, life of luxury are assured for him; Sun in this house means that again due to his own hard work and astute intelligence and courage, name, fame and even position of power would have been there or he would also run for political office easily had Venus not been debilitated in the 11th house. so that is why despite him having very strong political opinions and being involved in political activism – due to the multiple debilitated planets; he is not made for that level of fame and power. It will not suit his temperament because basically he has now turned into a reclusive person – despite name, fame as on a personal level he is having contact with very few close knit people. So I would say overall he has had to struggle a lot in his life; it has not been a easy life but due to the planets in all auspicious houses luck has helped him and the cherry on the cake is his marriage in 1971 at the age of barely 22 years to his wife whose chart analysis is below. They remain married with three children; so his chart analysis is incomplete without the chart analysis of the wife who is also a writer and they are a wealthy and known couple. And right now he’s going through his Lagna House Jupiter Mahadesha till 2032 and it is an overall good time and some amount of happiness from children is there; so the balance is so strong that while while Wifes Jupiter is debilitated; his is in the Laguna House; so they have three healthy children. So they they really made for each other kind of couple.

Analysis
So she is a strong ascendant Taurus; so while he is emotional she she is firm and smart about money. Saturn is retrograde and enemy in the 4th house; so career wise or as a writer; husband is much more known and Ketu in the sixth; so she is also in her own right doing well because of the planets that I will cover but professional luck comes from husband; so talent is there but the luck factor professionally is coming from the husband’s chart. She has mild Kaal Sarpa Dosha (MKSD); so professionally she will be a little mellow also or a little distracted; focusing more on the family but there are planets that will ensure that she does well professionally also and they become like a power couple. Jupiter debilitated and Moon in the 9th; so while her Moon is complimenting the husband’s debilitated Moon; her debilitated Jupiter is being balanced by the husbands lagna house auspicious Jupiter. Then Mercury in the 10th house of excellent. So for both of them Mercury is very well placed; means they are both very nice people; wealth is there; immense wealth is there in the chart of the spouse; life of comfort, authority and luxury is there. She may be managing his business. She may be the one who may be playing a greater role in managing the finance side of things because he is a very emotional kind of person. 11th house is super strong. Sun, Mars, Venus exalted. She is romantic, extreme lucky due to husband; happiness via marriage and she is balancing the husband’s debilitated Venus very well. She is highly intelligent and while the husband is a reclusive / is not so social; she is very social; the life of party kind of a person. So she manages the PR part of the family; they may be having a team because they both have powerful charts but for family functions she may be managing it and 12th house has Rahu; so this means there was basically she has settled very close to where she is born and right now she is also going through her exceedingly lucky Mercury mahadasha.
So in this case the couple are made for each other and we would not have this famous Stephen King without the active astrological role of his wife. And I would say that his birth chart is not scary; he has been through a lot but “Lady Luck” has helped. One of the most major decisions that one takes is marriage that that has been a very lucky event in his life and his planets also are in auspicious houses.
