Aunt Claire's Secret — Katie Evans

Sisters Isabel and Maya might fight like cats and dogs, but the one thing they can agree on is that Aunt Claire is hiding a big secret in her small-town veterinary clinic-and they're going to find out what it is. When Aunt Claire is kidnapped and her animals are stolen, the girls must work together to save her. But doing so could expose her top-secret research to the world and allow the data to fall into very dangerous hands. This tale of courage, wit, and sisterhood is perfect for fans of Minerva Keen's Detective Club.
