This new series of nonfiction readers will grab a student's interest from the very first page! Designed with reluctant readers in mind, these riveting 64-page softcover books offer short chapters on high-interest headlines. Each chapter is its own mini-book, which includes a timeline, key terms, and interesting facts. Fascinating black and white photographs keep the pages turning. A bibliography encourages further topical reading. When something or someone turns up missing, it is unexpected-often even a gripping mystery. Law enforcement professionals are skilled at tracking the missing. Sometimes, however, a disappearance is inexplicable. A spacecraft disappears millions of miles from Earth. A ship or plane vanishes in the Bermuda Triangle. What explains these mysteries?
