In The Glowing Heart, Josefina and her family, including her stepmother, Tia Dolores, are celebrating Three Kings Day. Joining the family are two visitors: Senor Fernando, who wishes to buy a horse from Josefina's father, and Don Javier, a former boyfriend of Tia Dolores, who brings her the ruby ring she has inherited from an aunt. When the ring goes missing, Tia Dolores is devastated and Josefina wonders which of their guests could have stolen it, and whether the family is in danger of losing anything more to the thief. I liked this book a lot for the day-to-day details of living on a ranch, but not as much for the mystery. For a kids' book, this involved a lot of adult characters with more mature problems than most eight-year-olds can relate to. I had never read a Josefina book, so this was interesting for that reason, but otherwise, it was really just okay.
