This is book two of The Flaca Files, and Detective Flaca is at it again! This time, Flaca is happy to receive all the tools that she needs for her case as Christmas gifts, but she is not happy that she also received plane tickets to Puerto Rico. She has a case to solve! However, she and her sister head to Puerto Rico anyway, to stay with their grandmother. There, she is faced with another case, the Case of the Three Kings. Three Kings Day is celebrated on January 6th, and involves three men who come around to leave gifts for children. This sounds suspicious to Flaca, so she decides to investigate. This bilingual book is great for young readers!
