This series takes a rational, scientific approach to cryptids, monsters, and the paranormal. Commendably, it does’nt debunk these phenomena, nor does it talk down to or ridicule believers. Short sentences promote fast-paced reading, ramp up suspense, and welcome striving readers. New vocabulary appears in boldface and is defined in the glossary. Volumes provide interesting historical information about what different cultures believe or believed about these phenomena. One chapter in each title brings investigations of the particular topic into the present day and explains what modern tools are used to investigate/explore it, and what some people believe and why. A subsequent chapter provides scientific, real-world explanations for the phenomenon. The series benefits from attractive design and visuals. Note: The vampire and zombies titles are a bit gruesome. VERDICT An appealing series recommended for schools and public collections.
