In Unexplained: Ghostly Encounters, readers in grades 5-9 will take a look at some of the scariest claims of ghostly encounters throughout history. Things go bump in the night, people see things they can't explain, strange figures suddenly appear and then vanish--are they real or imagined? 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.
