Evil, Inc.

Reach for this book when your child is seeking a more mature, high-stakes mystery that emphasizes self-reliance and sibling bonds. Unlike the classic series, this Casefiles entry is designed for the middle schooler who has outgrown cozy mysteries and wants a gritty, international thriller. The story follows Frank and Joe Hardy to France, where they are isolated from their usual support systems and must face a dangerous global crime syndicate. While the core values of justice and bravery remain, the tone is more urgent and the threats more realistic. It is an excellent choice for a reader who is ready to explore themes of independence and the complexities of fighting a 'faceless' corporate evil. It serves as a bridge to adult thrillers while remaining grounded in the unwavering loyalty between the two brothers.
