Note to readers of House of Mirrors

The genesis of House of Mirrors was a slip of the finger during searching for a book to read on my kindle. I inadvertently clicked on what was portrayed as an erotic story, mentally seeing the words as an exotic story. What I downloaded was a truly crude bit of pornography, written in language with which I am not comfortable. It was essentially street language that described sex acts in the crudest way, using crude language. I deleted it from my kindle.

That night, I began to think that over the years I have on occasion read erotic books, beginning as a boy with D. H. Lawrence’s Lady Chatterleys Lover and later on one with a semi-erotic theme Being There by Jerzy Kosinksi that was made into a movie starring Shirley McLane. I conflated that thought with the notion that I could write a more interesting erotic story than what I had inadvertently downloaded to my kindle. And that I could do it without using street language to describe self-love and other forms of amorous activity. I let my imagination rove and House of Mirrors is the result.

I submitted it under my pen name, Stanley Israel to VP Publications and their subsidiary sent me a contract to publish the work as a novelette. This little book is the result.

I published it under my pen name to avoid embarrassing family and friends who might be appalled that a man of my age and profession has and is capable of expressing such thoughts. If such material is offensive please do not purchase the paper back or download it for your kindle or nook.

The forthcoming, Love, Sex and Erotica deals with the same themes and people uncomortable with such material should avoid it.
