Editorial Review
A noteworthy review of Unsolved Mysteries from Horn Book Guide on April 1, 2016

4-6 Unsolved Mysteries series. These books offer clear-eyed assessments of persistent unexplained phenomena. An anecdote introduces the titular subject; each survey superficially touches on history and possible explanations— scientific or otherwise. The slight texts are easy to read and enhanced by captioned photos and ‘Myth or Fact?’ bubbles. The open-ended discussions allow readers room to reach their own conclusions. There are four other fall 2015 books in this series. Reading list. Glos., ind.
