This dictionary on Classical Mythology, i.e. Greek and Roman, is incredibly accessible to any level of reader. The information is presented clearly with just enough detail for clarity. A reader does not need to be well versed on a given character or story to gain great insight from this text.
The only reason give this book 4 stars is not because of the material presented, but the materials used to produce the book. Like most books of this type, they are value priced. As a result, the materials can be sub-par. In the copy that I have, the pages are overly thin and the print bled through in some places.
