Booklist

The Mysterious & Unknown series walks a fine line, presenting information that a student could use to write a report without throwing too much cold water on good old-fashioned, shivery stories. They end up leaning more on the side of stories, although they do cite where the information comes from in chapter notes. Sorcery discusses the history of wizards, focusing on black magic; for the most part, it skirts the topic of witchcraft. Each book includes drawings, etchings, photographs, and other artwork, though the sidebars and boxes sometimes repeat information from the main text rather than extend it.— Susan Dove Lempke
