This is a stepbrother / stepsister taboo romance that has a MMC that is a Germaphobe as the title suggest. But the one person that he can stand to touch or have touch him happens to be his younger stepsister. Callie Moss does a great job helping you get into the MMC's mind and see the origins of how he got the way that he did all giving you a tension build up between step siblings after the loss of their parents. This is dark and very taboo. 10 out of 10 would recommend.
