People are intrigued by conspiracy theories—even if they don’t believe them. This well-done series, written in a conversational tone, will quickly grab and hold readers’ attention and help students learn to think about and question what they read and hear. Each title covers four conspiracy theories, a term that is defined early on. Chapters discuss how such theories start and are maintained, what researchers say, and how they’re debunked. Some examples are ludicrous and might make students chuckle while reading. However, the series admits some (more plausible sounding) theories are difficult to disprove and give pause, which allows scientists to ask questions and find out more. An important feature in each book poses questions that provide valuable ideas for student consideration. The series is visually attractive, with black-and-white and color photos and ­helpful captions. Some artwork is cartoonish, e.g., aliens and reptiles, and maps are included when needed. ­VERDICT Recommended for schools and public libraries. Absorbing, ­solidly evidence-based, and thought-provoking.
