This cover is absolutely cracking me up:
The story is one big ick-fest about a woman who was date-raped when she was 16, and had a secret baby. Now she’s dating a sweet younger man, who gets along with her kid like a house on fire. Then of course, this being Anne Mather, she discovers her boyfriend’s father is
her rapist the man she loves.
So we have… rape, faux incest, a huge age difference with one party an actual teenager… a trifecta of ick, we don’t even need sex in a clown mask.
The man in question is about 35 when they first meet, 45 when they meet again. So all I can conclude from looking at that cover is that it depicts the heroine with his son.
