In Unexplained: Freaky Phenomena, readers in grades 5-9 will explore a variety of unexplained phenomena. Is dance fever real? Can something be both a plant and an animal? Can a human simply burst into flames? 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.
