Are psychic powers real? In Unexplained: Psychic Powers, readers in grades 5-9 will explore psychic powers (such as Extrasensory Perception (ESP)), true psychic predictions, the importance of dreams, and much more. The Unexplained series is designed for readers to be able to flip through until an image catches their interest. Each 32-page book includes spreads that feature a handful of info-packed sentences. Quick tidbits mean the book doesn't have to be read cover to cover, making this series perfect for reluctant readers.
