Raymond Taylor is a happily married young man celebrating a promotion at a nightclub with friends. He foolishly lets his guard down when he meets an attractive young woman at the bar. Sally is overfriendly and buys a round, then asks Ray to take her home.
Crossing a deserted park, she cajoles him into undressing with a view to having sex on the grass. While kissing, Sally holds a sparkling pendant between their heads. Ray, drunk and confused, can't believe his eyes when instead of Sally kneeling on the grass before him, he sees himself.
His doppelganger delivers a punch, knocking out Ray, then hurries away. He/she wakes to find he possesses a young woman's body. The girl has a history of schizophrenia and he/she soon discovers that a part of Sally's character remains in her body.
From her first embarrassing medical examination, Sally discovers that living in a girl's body is one long nightmare, especially when she is treated by a depraved professional who should be taking care of her.
As well as an exciting storyline, this novel contains humiliating situations and explicit descriptions of sexual activity; and is therefore only suitable for mature readers over 18 years of age.
