This book offers quick tidbits, images, and information on people and places in history that have been involved in mysterious, unexplained disappearances.

In Unexplained: Mysterious Disappearances, readers in grades 5-9 will explore people and places throughout history that have been involved with sudden, mysterious disappearances. What happened to Amelia Earhart? Why is the Bermuda Triangle so mysterious? In some cases, theories can explain what happened. In others, no one is sure.

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.
