The book I’m looking for was published 1970s-1980s. It takes place in the country, and horses figure prominently.
The plot is that a 17-18 year old girl is in love with a slightly older man. They live on farms near each other. His family is wealthy and raises prize horses. Her name is Ellen, his is john Waters or Watson. She keeps coming by to watch him train horses, and eventually they have relations. After she tells him she’s pregnant, he goes away on business. Meanwhile his family’s prize horse is stolen, and vanishes. While Ellen waits for John to return, her pregnancy advances. At the end of the story, she goes for a walk, and by chance discovers the stable where the prize horse is hidden. She goes into labor, and barely makes it into the stable before she passes out. When she comes to, her baby boy is wrapped in a flannel shirt. John is there, and finally admits the baby is his.
I know this is a weird plot line, but can you help me remember the title? I’d love to have it if I could find it because it was a coming of age story for me.
