I’m looking for a book that I read as a young boy but whose name now eludes me. I have no recollection of the title but can provide some detail regarding the story and the cover art (at least the version I had).
The story is about a young boy who moves with his family (father and mother) from a city to a country farm/ranch, despite his initial misgivings. One of the first thing he experiences is a hunt for a mountain lion which has been killing livestock in the area. He sees a mother mountain lion killed and then two cubs thrown to a pack of dogs. Later, he finds a female, runt cub in the mountain lions’ cave (she was too weak to come out and, therefore, escaped notice). He takes her home and secretly raises her. I am fairly certain that he calls her “Beauty” but I am not 100% certain. The book continues with the boy raising the cub to young adulthood, including teaching her how to hunt. Near the end of the book, the father is injured and the mother is somehow incapacitated so the boy (and his secret mountain lion companion) have to walk several miles to town to get a doctor/medicine. Finally, the boy needs to release the mountain lion back into the wild. The book ends with their separation.
I believe the book was published by Scholastic Reader and would have been published sometime in the 1970’s (I think). The cover has artwork that shows the young boy crouching up on a rock to feed or pet the mountain lion who is standing on the top of the rock.
